I am a graphic designer who focuses on information design. My day job? Well, they asked me not to say. But to be clear, this blog is my something I do on my own time and does not represent the views of…my employers. I think what I can say is that given my interest in information design—be it in the shape of clear charts, maps, diagrams, or wayfinding systems—I am fortunate that my day job focuses on data visualisation. Outside of work, I try to stay busy with personal design work. Away from the world of design, I have become an amateur genealogist and family historian. You will sometimes see that area of work bleed into my posts.
Yesterday I mentioned how I spent Monday researching some old family properties in Philadelphia. In some cases the homes my family owned still stand. But, in many others the homes have long since been replaced. But that’s the nature of city development.
That got me thinking about an article published earlier this month at Philadelphia YIMBY where the author created an animated .gif detailing the Philadelphia skyline from 1905 through 2020. This screenshot captures the overlay of 2020 atop 1905 from the south of Philadelphia.
But the gem of the piece is the animation. Implicit in the graphic but unmentioned is the text, which is understandably centred on the architectural designs of the skyline, is the history of Philadelphia.
In the old days, well before 1905, the city was concentrated along the Delaware River because it was—and still is—a port city. But as those shipping businesses were replaced by banks and financial companies which were replaced by other offices and manufacturing headquarters that were themselves replaced by corporate highrises and so on and so forth, we can see the centre of gravity shift westward.
The mass of buildings by 1905 has shifted away from the Delaware River and is concentrated to the east of City Hall, the tallest building until the 1980s. But you can see the highest and largest buildings moving more to the left in every frame. Though in the latest you can see some new largely residential highrises built along the Delaware waterfront.
I took a holiday yesterday and headed down the street to the Philadelphia City Archives, which houses some of the oldest documents dating back to the founding of the colony. But I was there primarily to try and find deeds and property information for my ancestors as part of my genealogy work.
When I walked into the building—the archives moved a few years ago from an older building in University City into this new facility—an interactive exhibit confronted me immediately. Now I did not take the time to really investigate the exhibit, because I anticipated spending the entire day there and wanted to maximise my time.
But there was this one graphic that felt appropriate to share here on Coffeespoons.
Like a lot of statistical graphics from the mid-20th century we have a single-colour piece because colour printing costs money. It makes use of a stacked bar chart to highlight the share of housing in the city that can be classified as substandard, i.e. dilapidated or without access to a private bath.
The designer chose to separate the nonwhite from the white population on different sides of the date labels, though the scale remains the same. I wonder what would have happened if the nonwhite bars sat immediately below the white bars within each year. That would allow for a more direct comparison of the absolute numbers of housing units.
That would then free up space for a smaller chart dedicated to a comparison of the percentages that are otherwise written as small labels. Because both the absolutes and percentages are important parts of the story here.
The white housing stock increased and the number of substandard units decreased in an absolute sense, leading to a strong decline in percentages.
But with nonwhite housing, the number of substandard units slightly increased, but with larger growth in the sheer number of nonwhite housing units overall, that shrank the overall percentage.
Put it all together and you have significant improvements in white housing, though in an absolute sense there still remain more substandard units for whites than nonwhites. Conversely, we don’t see the same improvements in housing for nonwhites. Rather the improvement from 45% to 35% is due more from the increase in housing units overall. You could therefore argue that nonwhite housing did not improve nearly as much as white housing between 1940 and 1950. Though we need to underline that and say there was indeed improvement.
Anyway, I then went inside and spent several hours looking through deed abstracts. Not sure if those will make it into a post here, but I did have an idea for one over a pint at lunch afterwards.

Okay, technically not Spring Garden Street, but a strip mall along one of Philadelphia’s main arterial city streets. Luckily these aren’t some victims of a serial murderer, but rather the result of Philadelphia being an old city (for the United States). As this article from the Philadelphia Inquirer explains, the bodies were discovered during excavations for new construction at the site.
The reason I shared this today was that this past weekend, I had a pint with a colleague of mine at Yards Brewery located at 5th and Spring Garden. We sat at an outside table along Spring Garden and at some point I recall pointing out that Spring Garden hadn’t always been a street. Originally it only existed west of Broad.
Little did I know that the construction site across the street on that sultry Sunday afternoon was home to an archaeological excavation of an old, long since demolished city church cemetery.
You can use the slider in the article to compare the layout of the intersection in 2021 to that of 1860. I love these old timey maps, especially when working on genealogy. Because while we know the cities where we live today, they didn’t look like we know them 150 years ago. And in lieu of photography, it’s otherwise difficult to try and make sense of our ancestors’ world.
Just a few doors south of the Methodist church we had a bakery and a small alley called Brussels Place. And facing the alley we had what look like a number of small homes or perhaps stables. Larger presumably rowhomes lined the main streets of the intersection.
At the right of the screen, I also remember my colleague and I discussing some of the old-looking rowhomes. They may very well be the same ones depicted on this 1860 map. They are the few survivors as most of the area, as the article points out, was eventually turned into a petrol station that later became the strip mall today fenced off to be turned into flats.
So Mondays no longer work for these regular updates, because as we know Illinois no longer reports weekend data. Starting next week, neither will Virginia. Furthermore, keeping track of the vaccinations is tough, because the same. But also, then we have Pennsylvania, which includes Philadelphia, but Philadelphia only updates vaccination data twice per week.
Consequently, I’m not sure what I’m going to continue doing. But at the least, these updates of cases and deaths could continue, because after one cycle the zero numbers for Saturday and Sunday will average out.
The question is where are we today?
Well when it comes to new cases, we are seeing slight upticks across the board.
But whereas the upticks were slight last week in Pennsylvania and Delaware, they were a little bit greater this week. Still, we are far from drastic upswings, but they are noticeable. Look at the very tail end of Delaware and you will see a slight change in the curve’s slope. Pennsylvania’s is, for now, less noticeable.
In New Jersey, where cases had still been declining last week, the numbers are now heading back up. You can see this as well in the chart with a sudden little jump in the last day or so.
Meanwhile in Virginia and Illinois, the upward swings have clearly begun and they are plainly visible. But the numbers are increasing, because in Virginia today’s seven-day average is now the highest it’s been since the end of May. In Illinois, yesterday’s average was higher than today’s, but both are about the same as the average was in the beginning of June.
State departments of health indicate these increases are mostly all in unvaccinated people. And that’s not terribly surprising given that the new Delta variant beginning to take root in the United States is far more effective at viral spread than its predecessors. The worry is that the variant may be more lethal.
And to that point we are also seeing the seven-day average for deaths rebound in most states.
First, the exception. Delaware has now gone over a week without any Covid-19 death and its average now sits at 0.0.
In all other states, the trend is pretty clear if not visible in the charts. Illinois is the most obvious where the recent rise in deaths from Covid-19 can be seen in the sharp jump of the orange line at the tail end of the chart. The state is now flirting with double-digit death rates after hitting 11 and 13 deaths per day Sunday and Monday.
Elsewhere, we have numbers creeping up, but still below the levels we saw two weeks ago. On 28 June, Pennsylvania averaged 12 deaths per day. That had fallen to 5 for last week’s write-up, but today it sits at 7. New Jersey went from 8 to 4 but is back up to 5. And Virginia went from 6 to 3 and is now at 4.
Again, these are not catastrophic increases, to be clear. However, after several weeks of declining numbers of deaths the death rates are climbing once more. As with new cases, state departments of health point to the deaths being in the unvaccinated populations.
If you haven’t been vaccinated yet, I encourage you to do so. They have been proven both safe and effective. And if cost is your concern, they’re free. This new Delta variant can make you sick even if you’re only partially vaccinated—only one of the two required shots for Pfizer and Moderna. Factor in the month+ you need from your first of the Pfizer and Moderna doses through the second and the two-week waiting period, it’s critical you schedule your shots as soon as possible.
I’ll try to look at writing up the numbers again next Tuesday or Wednesday, and over the course of the week I’ll be following these numbers. Though I’m not entirely certain I’ll continue posting them daily to my social media feeds. (In fairness, I’ve been busy enough to preclude me from doing that the last two weeks.)
This is a piece I’ve been sitting on for a little while now, okay half a year now. There isn’t too much to it as it’s an illustration overlay on a satellite photo. But the graphic supports an article about the construction of a new roundabout in Philadelphia, coincidentally where I used to live.
That intersection is…tricky to navigate at best as a pedestrian because there are six and a half streets converging at the junction—I give a half to Arizona St because, well, you’ll see shortly. When I lived in the neighbourhood I saw several near accidents between vehicles and pedestrians and vehicles and cyclists. Anything to help improve the safety will be welcome. And that improvement is what the Philadelphia Inquirercovered back in January.
This definitely fits in the category of well done, small graphics. Not everything needs to be large and interactive. This does a great job by using transparency over the satellite image and layering illustration atop the photo.
Now if we could only restore the old rails on Trenton Ave to be some kind of tram/trolley or light rain corridor. Regardless, there are some good restaurants and drinks options in the neighbourhood, so maybe I’ll have to go investigate in person now that going out is an option again. You know, to a do a proper follow-up.
Earlier this week I was researching something for my day job that prompted me to look through an 1820 city directory for Philadelphia. Whilst looking for my information I came upon this graphic depicting how Ben Franklin advised people divide their time during the day.
Notably, this is all done in 1820, and so the typesetters used metal type, not graphics in our present-day sense, to create this. Although, that does leave room for a few issues of where these breaks actually occur. But overall this is remarkably similar to a day in the life in, well let’s just say January 2020 in the before times. An eight-hour work day with an hour’s break for lunch. And then four hours to yourself in the evening. Seven hours of sleep and then three hours to yourself in the morning.
Of course in the pre-electricity era, you can see how these times are focused around, you know, daylight. No lingering at the pub until well after midnight. It’s also notable how the emphasis on dining is at noon, not in the evening as we tend to do today.
Whilst this is billed as Franklin’s advice on how to structure your time, it should be pointed out that by 1820, Franklin had been dead just over 30 years. But that’s just one generation’s time removed.
Enjoy your weekend, everyone.

Air is an art project by Marina Vitaglione and written about by the BBC. The project seeks to raise awareness of the air pollution in and around London. She used cyanotypes to capture the pollution in the area. She collected evidence of the pollution in circular areas on paper and then exposed them as cyanotypes.
Cyanotypes work by exposing a piece of paper coated in a substance that, when exposed to sunlight, turns blue. The parts protected from sunlight, in this case the pollution, stay their original colour and you are left with what here is air pollution.
This screenshot from the article compares the air pollution in Lewisham on the left to Wembley on the right. As the author explained in the article the “aesthetic, the cyan-blue tone of cyanotypes remind me of pure, cloudless skies, contrasting with the vision of grey clouds we have when we think of air pollution”.
If you want to read more about the process or see more examples of her artwork, I recommend reading through the BBC article. Or, for my London readers, you can see the artwork in person as part of the Koppel Project Exchange’s show What on Earth.
In trying to limit my Covid-19 updates to Monday, bank holidays definitely affect the schedule. For my international audience, that meant Monday was a day of no posting. It also meant that some states—Illinois—were not reporting data. Add to that Illinois had already stopped reporting data on Saturday and Sunday, I wanted to wait until we had Tuesday’s data before putting it all together. And so here we are.
Last week I discussed “divergent patterns at the margins”. We saw some states continue their progress in decreasing the numbers of new cases with falls in their seven-day averages. You could group the tri-state area in this category. Then in the other group we had Virginia and Illinois where the seven-day average had begun to rise.
In the week since, this pattern largely held the same. Both Virginia and Illinois continued to see rising numbers of new cases. Compared to 20 June, before this pattern emerged, Virginia’s seven-day average sat at 129 new cases per day and Illinois was just slightly worse at 156. Yesterday those numbers were 180 and 328, respectively. A far cry from an emergency, yes, but also not ideal.
What about the tri-state area? Well we can now lump Pennsylvania and Delaware in with Virginia and Illinois since both states saw a rise in their seven-day averages. Back on 28 June Pennsylvania sat on an average of 177 new cases per day and Delaware was at 19. Yesterday those numbers were 181 and 27, respectively.
The difference here is that in both Pennsylvania and Delaware this recent rise is still below the numbers from 20 June. On that date Pennsylvania’s seven-day average was 261 new cases per day and Delaware’s was 28. So it’s not great, but it’s still not bad either.
How about New Jersey? The Garden State continues to see declining numbers of new cases. From the 20th to the 28th to yesterday the average has fallen from 179 to 176 to 162. Certainly not dramatic, but it’s progress nonetheless.
With deaths we saw broad and general progress, however, so that’s good.
Last week I mentioned how I had hoped we would see Pennsylvania’s seven-day average of deaths slip into the single digits. Instead it had climbed higher. Well, Pennsylvania finally fell into the single digits and rests at 5 deaths per day.
When we look at the remaining states we see good news across the board. In Illinois the seven-day average fell from 9 to 7 deaths per day. In two states the numbers fell by half. New Jersey fell from 8 to 4 and Virginia went from 6 to 3. Finally, Delaware now averages just 0.1 deaths per day.
I don’t have the data on vaccination, because there are some holes and I want to see if I can fill that data out. But in the three states we track, we are talking about less than a percentage point increase in fully vaccinated people over the course of over a week. That continues to be not ideal.
A little over a week ago the Philadelphia Inquirer posted an article about sharks. It wouldn’t be the American holiday of 4th of July without mentioning Jaws. Think of it, there really are no good Hollywood films about the Constitutional Convention or Declaration of Independence. I mean we have Mel Gibson’s The Patriot. But, that’s terrible. I digress, we’re here to talk about sharks.
A great white shark swam past the Jersey coast in mid-June. She swam just off the shore of Atlantic City’s beaches before moving on towards a shark nursery in more northern waters near New York and New Jersey.
Why are we discussing it? Because sharks have always fascinated me. It’s my blog. Oh, and it had a map.
There isn’t much to say about this map, it makes a good use of contrasting red for the shark’s path against the light blue of the ocean.
Hopefully none of you were eaten by a shark over the holiday.
