Boston Beer Company is the parent company of Sam Adams, which is definitely one of those beers I imbibe when I visit Boston. But, as one of the larger craft brewers in the United States, it finds itself under immense competition. This article from Bloomberg examines the situation the brewery finds itself in from a share price, growth, and revenue standpoint.

You clearly didn’t miss this story from two weeks ago, because we all had to change our clocks. But, you might not have thought much about it. Which is fine, because I think there was an election or something a day or two later. Or was I dreaming/nightmaring?
Thankfully Andy Woodruff did think about it and he put together a really nice piece about how the changes to time affect the amount of perceived sunlight. I say perceived because obviously the same amount of sunlight falls upon the Earth, but it’s whether we can see it from underneath the covers or hidden behind our office computer monitors.
His interactive piece lets you examine scenarios based on your preferred inputs. For example, as someone who goes to work a bit later in the morning—I have to write this blog sometime, right?—I would prefer the sun to be up later into the evening. And based on my selections, that means that I should consider the argument for always using Daylight Savings Time.
Whereas if I valued a sunrise with daylight, I might prefer to abolish Daylight Savings Time.
Well this is it. Well at least for you American readers of this blog. It’s Election Day. If you had told me that this is what it would come to almost a year and a half ago, I would have laughed. But it did. And now it comes down to all of us to vote, unless unlike me you live in a state with early voting. And then when the polls begin to close, nerds of the political and data persuasion will be following the results in state, counties, and congressional districts.
And we will be following it all because not all the people on the ballots are named Trump or Clinton. I lived eight years in Illinois. There, you guys are, among others, choosing between Kirk and Duckworth. Here in Pennsylvania, it’s between Toomey and McGinty. Here there is also a referendum on judicial retirement ages. Other districts, counties, and states will have other things upon which to vote.
And while local politics and governance impact us the most, let’s face it. We’re all here for the title fight. The heavyweight class: Trump v. Clinton. So today being Election Day, how is it going to turn out? Well I have my thoughts, check them out here, but who really knows? But who also doesn’t want to try and guess? Enter the New York Times. They have a great interactive decision tree that allows you to experiment. But even without selecting a thing you can see how much more likely a Clinton victory is. She simply has more paths to 270 electoral college votes.
But that all said, a Clinton victory is far from guaranteed. If the narrow polls are wrong in any one of her “firewall” states, Trump can win. And while it may seem forever ago, remember Bernie Sanders in Michigan? The polls had him down by at least five points to Clinton throughout the race. He won the state by two points. Now a seven point swing is a bit extreme, and I am not suggesting any state will be in that much error. But three to four points is very plausible. And Clinton’s leads? In many of these states, they are within that uncomfortable margin. So here is a plausible scenario that makes tiny New Hampshire and its four votes the deciding state.
So remember, if you haven’t already, go vote. And if I learned anything from Chicago, it’s vote once, vote often.

Well, everyone, today you get two posts. The first and earlier (and planned) post is about polling in Pennsylvania. Relevant to those of you following the US election. But today’s post is about what trains are running in the city of Philadelphia.
If you haven’t heard, the city’s mass transit agency, SEPTA, and its primary union for workers within the city cannot come to an agreement on a contract. So…strike. And for those of you reading this from outside the Philly area, rest assured it’s just chaos right now. To put it into a wee bit of perspective, we have this graphic—actually an interactive map—of train routes in the city. And by train, Philadelphia has your standard suburban commuter heavy rail and subway lines and light rail lines, but we also make use of a number of trolley lines.
What the map does not show are the city’s various bus routes, all of which that run within the city are suspended. There are bus routes and rail lines outside the city, most notably the commuter rail or the blue lines in the map, operated by a different union that is not on strike.

Well the election is next Tuesday, and last Friday and this past weekend was…interesting. So one(ish) week to go, and we are going to turn to a few posts that use data visualisation and graphics to explore topics related to the election.
Today we start with the latest tracking polls, released on Friday. The piece comes from the Washington Post and highlights the closing gap between Clinton and Trump with a sudden spike in Republican candidate support. But what I really like about the piece is the plot below. It displays the 0 axis vertically and plots time with the most recent date at the top. And then support for the various demographics can be filtered by selectable controls above the overall plot.
Of course the really interesting bit is going to be how much this changes in the next seven days. And then what that means for the results when we all wake up on Wednesday morning.

How much does a gallon of milk cost? That, of course, is one of the classic election questions asked of candidates to see how in touch they are with the common man. But the same can be understood by enquiring whether or not they know how much a gallon of petrol or gasoline costs. And Bloomberg asked that very same question of the United States relative to the rest of the world. And as it turns out, here in the States, fueling our automobiles is, broadly speaking, not as painful as it would be in other countries.
The piece includes the below dot plot, where different countries are plotted on the three different metrics and the dots are colour coded by the country’s geographic region. But as is usually the case with data on geographies, the question of geographic pattern arises. And so the same three metrics presented in the dot plot are also presented on a geographic map. Those three maps are toggled on/off by buttons above the map.
A really nice touch that makes the piece applicable to an audience broader than the United States is the three controls in the upper-right of the dot plot. They allow you to control the date, but more importantly the currency and the volume. For most of the world, petrol is priced in litres in local currencies. And the piece allows the user to switch between gallons and litres and from US dollars to the koruna of the Czech Republic.

Yes, ISIS does receive a lot of attention in the media and during the presidential debates. But you might be surprised to learn that actually the organisation has lost a significant amount of territory lately. This BBC article details the territorial changes through a nice interactive map slider.
You could create a single map showing the losses/gains instead of using this light-duty interactive piece. And to the BBC’s credit they did. However, between the image quality and territorial changes, I think in this instance the interactive piece does add clarity to the story.

Yesterday scientists announced the discovery of a likely rocky planet within the habitable zone of Proxima Centauri, Sol’s (the Sun’s) nearest star. The New York Times covered the discovery with a piece full of nice explanatory graphics.
Now if we can only get onto the whole matter–anti-matter warp engine thing we could go explore the place.

Another day in Philadelphia, another post of Philly data visualisation work. Here we have a piece from 2015 that was updated earlier this spring. It looks at overdose rates in the Philadelphia region, including parts of New Jersey. It does include a map, because most pieces like this typically do. However, what I really find interesting about the piece is its use of small multiple line charts below to take a look at particular counties.
The piece overall is not bad, and the map is actually fairly useful in showing the differences between Jersey and Philadelphia (although why New Jersey is outlined in black and the Philly suburban counties are not I do not know). But I want to take a look at the small multiples of the piece, screenshot below.
You can see an interesting decision in the choice of stacked line charts. Typically one would compare death rates like for like and see whether a county is above, below, or comparable to the state, local, or national averages. But combining the three gives a misleading look at the specific counties and forces the user to mentally disentangle the graphic. I probably would have separated them into three separate lines. And even then, because of the focus on the counties, I would have shifted the colour focus to the specific counties and away from the black lines for the national average. The black is drawing more attention to the US line than to the county line.
I am on holiday for a few days and am visiting Philadelphia. So what better time to cover some Philadelphia-made content? This interactive piece came out last year from Philly.com alongside coverage of the Philadelphia mayoral contest.
I want to call out the colour palette for the choropleth in particular. We can see a blue to red system with a stop at yellow in the middle—a divergent palette. With this kind of a setup, I would expect that yellow or the light blue to be zero or otherwise straddle the point of divergence. Instead we have dark blue meaning 0 and dark red meaning 401+. The palette confuses me. It could be that the point of divergence—something around the 200 number—could be significant. It could be the city average, an agreed upon number for good neighbourhood relations, or something. But there is no indication of that in the graphic.
Secondly the colour choice itself. I often hesitate using red (and green) because of the often-made Western connotation with bad. Blue here, it works very well with the concept of the thin blue line, NYPD blue, blue-shirted police. If we assume that there is a rationale for the divergent palette, I would probably place the blue on the high-end of the spectrum and a different colour at the negative end.
Lastly, from the perspective of the layout, Philly has a weird shape. And so that means between the bar chart to the right and the city map on the left the piece contains an awkward negative space. The map could be adjusted to make better use of the space by pointing north somewhere other than up.—why is north up?—to align the Delaware River with the bars. Or, the bars could abut West Philly.
The interactions, however, are very smooth. And a nice subtle touch that orients the reader without distracting them is the inclusion of the main roads, e.g. Broad Street. The white lines are sufficiently thin to not distract from the overall piece.
