Kilauea Eruption

As a kid, volcanoes fascinated me. The idea that the molten core of the Earth can bubble its way up to and then erupt from the cold crusty surface of the planet still fascinates me. Of course, volcanoes can also have drastic impacts on people, both at the grand scale of impacting global climate to the smaller and more personal scale of someone’s home destroyed by a lava flow.

And unfortunately for residents of Hawai’i that personal destruction is unfolding across a development called Leilani Estates. The Washington Post has a nice piece detailing the geography of the area and showing how quickly things can change.

The article uses the photo above to illustrate the distance the lava flow travelled in only a few days. It also shows how precariously sited the homes are.

Only because I am so fascinated by these kinds of stories, I hope the Post continues to expand its content with pieces like this exploring the eruption and those of other volcanoes in the area.

To Infinity—

Wait, wrong film.

No, this weekend is Infinity War. Which is definitely not led by a Buzz Lightyear. For those of you who don’t know, Infinity War is sort of the culmination of ten years of Marvel superhero films, called the Marvel Cinematic Universe, that started with 2008’s Iron Man. Infinity War is the 19th film and brings together more than 30 main characters—and I believe I’ve read elsewhere as many as 85 when you count minor/side characters—into one two-part film. Yes, this will undoubtedly end on a cliffhanger leading into next year’s film.

If we assume each film is two hours (and I don’t think a single one has been under two hours), we are talking about 38 hours of film to watch to catch up before Friday’s release. Because both the previous Avengers films were 2h20m, I think we can round that up to at least an even 40. You know, a full work week.

Well, if your bosses won’t let you watch Marvel films all week, the Washington Post put together a nice interactive timeline that tries to sum it all up for you.

All the characters…but far from true.
All the characters…but far from true.

What is really neat about the piece, beyond helping me recall just what happened ten years ago, you can filter the timeline based on character and major plot points.

What would be really neat, though I assume someone has already done it, is a social network map showing how all these disparate groups were before this weekend’s film. Get on that, internet.

Tech Economies in the USA

Earlier this March the Washington Post published a piece looking at the twenty finalist contenders for the second Amazon headquarters. Specifically it explored how the cities rank in metrics that speak to a city’s technology and innovation economy.

That in and of itself, while incredibly fascinating, is not noteworthy in and of itself. Though I will say the article’s online title is neatly presented, split half-and-half with the vertical graphic showing the cities ranked.

I really like how this title space received a special design.
I really like how this title space received a special design.

But the point that was really neat was the interactivity that followed. Here you can see a dropdown from which the user selects a city of interest—surprise, surprise we are looking at Philadelphia. From that point on, the piece keeps the selected city highlighted in every graphic that follows.

Looking at Philly
Looking at Philly

Again, that is nothing truly surprising, but it is neat to see. What would have taken it to the next step is if each of those associated paragraphs were tailored to the specific city. Instead, they appear to be general paragraphs.

But overall, it does a really nice job of comparing the twenty cities—it’s actually fewer because both Washington and New York have multiple sites per metro area—across the different metrics.

The only part that left me scratching my head a bit was the colour choice. I am not certain that it needs the blue-green to yellow-green palette. Those colours seem defined by a city’s placement on the overall list and I am not convinced that the piece would not have still worked if they had been only a single colour, using another colour to define the selected city.

Pennsylvania 18th Congressional District: The Special Election

Today is Tuesday, 12 March. And that means a special election in the 18th congressional district of Pennsylvania, located in the far southwest of the state, near Pittsburgh.

Long story short, the district is uber Republican. But, the long-time Republican congressman, the avowedly pro-life type, was caught urging his mistress to abort their unborn child. Needless to say, that did not go over so well and so he resigned and now here we are with a veteran state legislator and veteran who calls himself “Trump before there was Trump” running for the Republicans and another veteran but also former federal prosecutor involved with fighting the opioid epidemic running for the Democrats.

Now about that uber Republican-ness. It is so much so that Democrats didn’t even run candidates in 2014 and 2016. And then in 2016, Trump won the district by 20 percentage points. But the polls show the Republican, Rick Saccone, with a very narrow lead within the margin of error. That in and of itself is tremendous news for Democrats in Pennsylvania. But what if Conor Lamb, the Democrat, were to actually somehow pull off a victory?

Well the Washington Post put together a great piece about how it really might not matter. Why? Because of that whole redistricting thing that I talked about. Neither Saccone nor Lamb live in the district that will replace today’s 18th.

The piece has several nice graphics showing just how much this area of the state will change and how that will impact these two candidates. But my favourite piece was actually this dot plot.

That's an enormous gap for Lamb to overcome
That’s an enormous gap for Lamb to overcome

It speaks more to today’s election than the future of the district. Everyone will undoubtedly be looking to see if Lamb can eke out a victory of Saccone this evening. But even if he loses narrowly, the Democrats can still take a glimmer of hope because of just how insurmountable the challenge was. It would require an enormous swing just to crack 50.1%.

Gerrymandering Pennsylvania Part IV

Yesterday the Pennsylvania Supreme Court published the new congressional district map of Pennsylvania, the latest chapter in this tale. Republicans in the state legislature have already said they will take this to the federal courts, but they tried that just a few weeks ago and the Supreme Court refused to hear the case.

So the Washington Post put together a map showing precinct-level data aggregated to the new borders and the result is a far more competitive map. Despite there being more Democrats in Pennsylvania, overall the map still remains leaning towards Republican, but there are more light blue and red, again meaning competitive, districts to be fought over.

Well now we have some sensible lines…
Well now we have some sensible lines…

I did hear on the radio this morning, however, that one implication will be in the new Pennsylvania 4th, which is comprised mainly of the Philadelphia suburban county of Montgomery. Right now, that area is so gerrymandered that there is not a candidate right now living with the new borders.

The Memo

So last week the House of Representatives published a highly controversial memo by Representative Devin Nunes. Why controversial? Because it is apparently missing dozens of pages of additional facts, data, and context. But what the memo does contain are connections between people and things. And this Friday piece from the Washington Post does a good job of trying to explain those connections.

It's just missing a lot of other details…

Jones–Moore Election Results

Apologies for the lack of posts over the last week or so, I have alternately been on holiday or sick while spending other time on my annual Christmas card. This will also be the last post for 2017 as I am on holiday until the new year. But before I go, I want to take a look at the election night graphics for the Alabama US Senate special election yesterday.

I am going to start with the New York Times, which was where I went first last night after returning from work. What was really nice was there graphic on their homepage. It provided a snapshot fo the results before I even got to the results page.

The homepage of the New York Times last night

The results page then had the standard map and table, but also this little dashboard element.

I'm spinning my wheels…
I’m spinning my wheels…

We all know how I feel about dashboard things. To put it tersely: not a fan. But what I did enjoy about the experience was its progression. The bars below filled in as the night progressed, and the range in the vote-ometers narrowed. But that same sort of design could be applied to other graphics representing the narrowing of likely outcomes.

The second site I visited was the Washington Post. Like the Times, their homepage also featured an interactive graphic, another choropleth map.

A different page, a different map
A different page, a different map

There are two key differences between the maps. The Times map uses four bins for each party whereas the Post simplifies the page to two: leading and won. The second difference is the placement of the map. The Post’s map is a cropping of a larger national map versus the Times that uses a sole map of the state.

For a small homepage graphic, bits of both work rather well. The Times cuts away the unnecessary map controls and neighbouring states. But the space is small and maybe not the best for an eight-binned choropleth. In the smaller space, the Post’s simplified leading/won tells the story more effectively. But on a larger space that is dedicated to the results/story, the more granular results are far more insightful.

On a quick side note, the Post’s page included some context in addition to the standard results graphics. This map of the Black Belt and how it correlates to regions of Democratic votes in 2016 provides an additional bit of background as to how the votes played out.

Note, the Black Belt was named for the black soil, not the slaves.

The Demilitarised Zone

Over the weekend, the American and North Korean leaders got into an argument with the North Korean leader calling President Trump old and the American leader calling Kim Jong Un short and fat. High class diplomacy.

So what holds the North Korean army, by numbers likely not quality one of the largest armed forces in the world, back from sweeping down the Korean coastlines and overrunning Seoul? Well, that would be the role of the Demilitarised Zone, or DMZ. And thankfully yesterday, whilst your humble author was out sick, the Washington Post published a piece looking at the DMZ.

The piece uses a giant, illustrated in the background to provide context to the words and imagery sitting in the foreground. (That is how I justified covering it in the blog: map.) Overall the experience was smooth and informative about the sheer amount of destructive power waiting just miles north of Seoul.

Flaking Out of the Senate

This has been a busy week. I am working on a small piece on the Red Sox managers in the free agency period—I thought it would be ready yesterday, but not so much—but news continues to happen outside of the baseball world. Some of the biggest, at least in the US, would have to be the speech by Senator Flake of Arizona who announced he would not seek re-election in 2018.

So cue the politically-themed graphics. Today’s piece comes from the Washington Post. The graphic itself is not terribly complex as it is a scatter plot comparing the liberal/conservativeness of senators with how their respective state voted in 2016.

Scrolling through the piece changes the graphic
Scrolling through the piece changes the graphic

But what the piece does really well is weave a narrative through the chart. Scrolling down the page locks the graphic in place while the text changes to provide new context. And then different dots are highlighted or called out.

It proves that not all the best graphics need to be terribly complex.

Earthquake Early Warning

Last month, two massive earthquakes devastated Mexico. Now, if you were like me, you were captivated by the photos and videos of the quakes striking and tearing down buildings and infrastructure. But, think about it for a second, how did people know to take out their mobiles and record the tremors for posterity’s sake?

Well, the first thing you should know is that earthquakes consist of a number of different waves of energy. Some move quicker and are less damaging than the slower travelling ones. And it turns out that scientists have been able to use that speed differential to build early warning systems along and around fault lines.

The Washington Post did a really nice job of explaining how earthquake-prone California is developing just such a system to deal with its tremors. I won’t spoil all the details, you should go read the article if earthquakes are of any interest to you.
