Baseball: The Bouncier Edition

Baseball is finally back as Spring Training continues to push through March, getting us closer to Opening Day. But one lingering question from last year remains: why the increase in power and home runs? While Major League Baseball (MLB) says there has been no change to the baseball, many think otherwise.

FiveThirtyEight published a piece looking at the insides of eight baseballs, four predating the power surge, which began after the 2015 All Star Game, and three balls since in addition to a newly manufactured and unused ball.

The piece uses a few graphics to showcase the differences, including this cutaway diagram highlighting the different layers of a baseball.

But the real gem is the X-ray photography done to examine the balls without cutting into them. Thankfully for those of us unfamiliar with x-rays, the designers provided a legend showing the clearly different core densities in the balls.

If you are interested in baseball, and in particular the increase in home runs, the whole article is worth the short read. And if you’re not, well, the x-ray views of baseballs are still pretty neat.

Italian Election Results

Europe enjoyed some significant political news yesterday. First, Angela Merkel will serve a fourth term as chancellor as the SPD members voted to allow their party to enter into a grand coalition with Merkel’s CDU/CSU party.

But the more important story is that of the Italian elections, where the centre-left under Matteo Renzi was attempting a comeback against the populist parties the 5-Star Movement and the League, the latter an anti-immigrant party. Also in the mix was Silvio Berlusconi, whose Forza party won 14% of the vote and as a member of a right/centre-right bloc that won 37%.

So I chose to highlight the homepage of IL Sore 24 Ore, an Italian newspaper, that had the results displayed clearly.

Of course the big problem is that I can neither read nor speak Italian. So figuring out just what every label is proved to be a bit tricky. But once you figure it out, it is quite clear.  The nice blue banner for the real-time results (again with the assuming of translation) does a nice job of clearly separating itself from the rest of the page, but the tables inside are quiet and not screaming for attention. Instead the user is allowed to find his or her party of bloc of interest and then scan to the right for the bold number of seats in the respective chamber.

The results page is similarly nice, using clean and simple tables to organise the information. Using the Chamber of Deputies page as an example, the overall results appear on the left while important context via maps and specific regions appear to the right. All the while the use of simple typography and whitespace guide the user to the appropriate data set.

And lastly a screenshot of an article about the election results, none of which I can read. Here, instead of an interactive table or graphic, we have a static graphic showing the results. It certainly captures the results in this particular moment—exact seat numbers have not yet been released—but could grow stale as the day goes on. Although there very well could be a page with interactive results like this, but that I cannot find because, again, I cannot read Italian.

The design of the graphic is nice. It uses the popular half-circle arc to show who “crosses the finish line” in terms of blocs seating more than 50% of the chamber. But once again, I am most impressed by the clarity of the table and information displays through white space and typography. (Though I feel in this case white space should be more like light salmon-coloured space.)

Overall, the designers did a fantastic job of presenting the data and information, so well that a non-Italian could even figure it out.

When No Change or Growth Is the Story

For many years I would often tell people that sometimes a visualisation can be “boring”, because the data itself is boring—a lack of growth in a market, no real mergers, or even steady and consistent but unspectacular growth. Those can all be stories, even if they likely result in very monotone choropleths or straight line charts or perfect steps of bar charts.

And then there are times when the lack of growth or change, when visualised, can be very powerful. I wanted to share this piece from the New York Times with everyone because it does just that.

You really need to click through and see the scale and scope, because the designers behind this did a fantastic job of capturing that sense of lack of change in a very large and expansive piece.

Undersea Mining

Today’s piece isn’t strictly about data visualisation. Instead it’s a nice article from the BBC that explores the nascent industry of undersea mining. What caught my interest was the story of Soviet submarine K-129, which sank mysteriously in the middle of the Pacific. But that isn’t even half the story, so if you are interested go and read the article for that bit.

But that sinking may have created the beginning of the undersea mining industry. And so as I read on, I found a nice mixture of text, photography, and graphics explaining processes and such. This screenshot is a comparison of the size of an undersea mining zone compared to a land-based copper mine.

Some of the graphics could use some polish and finesse, but I do appreciate the effort that goes into creating pieces like this. You will note that four different people had to work together to get the piece online. But if this is perhaps the future of BBC content, this is a great start.

US Olympic Performance

I don’t know if you heard, but the Winter Olympics just concluded. I’m admittedly not a huge fan of the Winter Olympics, but that doesn’t mean I didn’t keep my eye on some of the stories coming out of the coverage. One that I liked was this piece from FiveThirtyEight.

US performance was lagging at this point

It was about halfway through the Olympics and the US was not doing terribly well. The chart does a great job of showing how various countries were performing, or over- or under-performing, their expected total medal winnings. It did this through a filled bar chart with a bar-specific benchmark line. It was a nice combination of a couple of different techniques to incorporate not just the usual above or below the trend, but also the actual amounts.

Changes to Immigration Enforcement

Almost two weeks ago I read a piece in City Lab that used three maps to look at the changes to immigration enforcement in the first year of the Trump administration. I was taken by this final map in particular.

Some geographic patterns do emerge…
Some geographic patterns do emerge…

While the map does have some large areas of N/A, it still does show some interesting geographic patterns. I think New York showcases it the best. Counties that are less involved in enforcement operations are in the southern part, near New York City. But then you can begin to get a clear sense of what is “upstate” by that break roughly parallel to both the Connecticut and Pennsylvania northern borders.

To a lesser extent you can see the same pattern play out in Pennsylvania. While far more white—as in no change on the map—the counties of orange—more involvement—are located in the interior and western counties. That is perhaps somewhat in the same space as Pennsyltucky.

Immigration is clearly an engaging topic these days, and I found this map interesting not because of its design, but because of the geographic stories it tells.

The 2017–18 Flu Season

Last week I covered the Pennsylvania congressional district map changes quite a bit. Consequently I was not able to share a few good pieces of work. Let’s hope nothing goes terribly wrong this week and maybe we can catch up.

From last Friday we have this nice piece from FiveThirtyEight looking at the spread of influenza this season.

Red is definitely bad
Red is definitely bad

The duller blues and greens give way to a bright red from south to north. Very quickly you can see how from, basically, Christmas on, the flu has been storming across the United States. It looks as if your best bets are to head to either Maine or Montana. Maybe DC, it’s too small to tell, but I kind of doubt that.

As you all know, I am a fan of small multiples and so I love this kind of work. To play Devil’s advocate, however, I wonder if an interactive piece that featured one large map could have worked better? Could the ability to select the week and then the state yield information on how the flu has spread across each state? I am always curious what other other forms and options were under consideration before they chose this path.

It’s Friday, Can I Drink Yet?

Happy Friday, everyone. We made it through to week’s end. And you know what that means. It’s time for a drink. Thanks to one of my best mates for sharing this comic from Saturday Morning Breakfast Cereal.

He shared it with the comment: “I now understand your love of gin.”

Gerrymandering Pennsylvania Part V

Yesterday we looked at the new congressional district map here in Pennsylvania, drawn up by the state supreme court after the Republican legislature and Democratic governor could not come to agreement.

Also yesterday, FiveThirtyEight explored the redrawn map in more detail to see if, as I’ve read in a few places, the new map is a Democratic gerrymander. In short, no. The article does a great job explaining how, basically, it might seem like it because more Democrats are predicted to be elected based on various models. But, that is only because the map was so extremely gerrymandered in the past that any effort to increase competitiveness or fairness would make Republicans more likely to lose seats.

This one table in particular does a nice job showing just how in an average election cycle there are only four seats that you could consider reliably Democratic whereas there are six that are reliably Republican. And keep in mind that Pennsylvania actually exhibits the reverse split—there are more Democrats than Republicans in the state. So even with this new map, the state exhibits a slight Republican bias.

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.
