small multiples – Page 16

Women Bankers

…and not just any bankers but central bankers (the ones who establish policies at a national level), are rather under represented as this graphic from the Economist details. It is a nice use of small multiples with bar charts over time. Each bar is a 0–50% of the total membership of a central bank board and the share that is dark represents the number of women. Clearly for the countries selected not a single one has had a board of more than 50% women. Sweden and South Africa are the only two countries shown that have had 50% participation from women central bankers—though Norway and Denmark (for a period of time) have been consistently close.

Riding the Rails

A little while ago the Washington Post published this graphic on Metro ridership. But not just anybody’s ridership, that of the individuals who sit on the DC transit agency’s board. After all, should not those overseeing Washington’s transit agency be intimately familiar with the conditions faced by DC commuters?

How agency board members ride their transit agency…

The graphic is a really nice use of small multiples and shading and tinting to indicate which lines are travelled by specific persons. An icon of a bus denotes bus ridership. This is a very good piece.

Corporate Taxes

Corporate taxes are always a fun discussion point. Who pays too much? Too little? Not at all? In May, the New York Times published an interactive piece examining US companies and their effective tax rates from 2007 through 2012.

At its core, the piece is a bubble chart along one axis that plots the tax rate for the company, with the bubble sized proportionally to said company’s market capitalisation. Colours reinforce the tax rate plotting, but are not themselves necessary. I think they would have been better tied to something along the lines of industries or profit or sales growth.

Of course that was when I saw the button for viewing the data by industry. The view of all companies is broken up into a series of charts about each particular industry. And of course, if you want information on a particular company, the smart search/filter is particularly useful.

Gay Acceptance

Last week I looked at a piece from the Washington Post about the possible impact of the Supreme Court rulings on gay marriage in the United States. But with the rulings yesterday, we step back and look at globally how the progression of gay rights has taken steps forward or backward.

The National Post looked at the reversal of bans of gay marriage as well as polling from several countries to look at changing opinions and perspectives across the world. Fascinating/horrifying are some of the stories about specific countries in the map.

My only real criticism is that the colour-coding of regions seems a bit jarring. I wonder if grouping countries by region would not have allowed the same data to be presented in a bit quieter tone.

The Massachusetts Special Election

As I have been blogging the past several days, today the Supreme Court will announce its rulings on the two gay marriage cases. But, I have already looked at that twice now. Today I want to look at the results of the Massachusetts special election for the US Senate, necessitated by John Kerry resigning from the seat to become Secretary of State.

This work comes from the Huffington Post. It offers the usual map fare with towns coloured by the victor and tinted by the share of the vote. Though do note the interesting—is this novel?—means of filling in the town with colour to represent the percent of the town reporting. My screenshot is a bit late, but check out Warren near Springfield or Boston and Cambridge—a bit harder to see because of their size and shape.

Looking across the state for the results

However, the fascinating thing is the use of the small multiples of scatter plots to look at historic elections. The designers included a small key in the upper-right explaining that dots above the line represent towns where Ed Markey, the Democrat who won, outperformed the historic Democrat. I have not seen anybody attempt to portray the data in this fashion before.

Dambusters

More formally known as Operation Chastise, the Dambusters Raid occurred just over 70 years ago on 16 May 1943. That night, 19 RAF Lancaster bombers flew over the English Channel with the objective of busting open three dams to flood and cripple the electricity- and water-supplies to the all-important German Ruhr industrial valley.

Canada’s National Post looked at the bombing raid not just because of the story but also because the unit consisted of not just British airmen, but also those from Canada along with Australia and New Zealand. Per usual, their graphics team did an excellent job illustrating the details of the raid. They traced the route, explained how the unusual bombs were carried, released, and detonated and then looked at the success of the mission.

Changes in Global Life Expectancy

Today’s post is a scatter plot from Thomson Reuters looking at changes in global life expectancy since 1990. What is really nice about this piece is the main space for the data visualisation presents all of the data for all of the available countries. Beneath the main visualisation, the designer chose to use small multiples of the same chart to highlight broader regional trends.

Strikeouts on the Upswing

Strikeouts are an important part of baseball. They are the moments where the pitcher wins the duel between pitcher and batter that is the essential element of baseball. But over the years the game has seen more and more batters striking out more often. Earlier this year the New York Times looked at the rising rates of strikeouts in a story supported by interactive data visualisation components.

Like the piece on Bryce Harper, this piece on strikeouts is more of a narrative with the interactive graphics supporting the written words. It is not as lengthy as the Washington Post’s piece, but this one is far more interactive as the user can select his or her favourite teams and follow their performance over time.

Bryce Harper

Bryce Harper is undoubtedly one of the best baseball players in the game today. To put it simply, he hits. And he hits well. And he hits well often. So the Washington Post put together an interactive, long form piece about Harper’s swing and hitting.

The piece begins with a narrated video outlining the science behind Harper’s swing. Then the reader can down into the piece and learn more about Harper’s history and development and how he compares to other hitters. Statistics and data visualisation pieces show just how impressive Harper is as a hitter and how pitchers are trying to combat that.

Interactive long form articles are appearing more and more often online. But this is perhaps the most data- and science-intensive piece I have seen thus far. What is particularly nice about the format is that, as I have often noted, annotations and explanations are what make good infographics and what move data visualisation from presentational to informational. That this piece in particular happens to be about baseball, well, all the better.

More Cicadian Rhythms

On Tuesday I shared with you some work by Jonathan Corum at the New York Times on the 17-year cicadas now starting to emerge back east. (And as I recall from my childhood, I assure you that they are quite loud.) Today we look at an illustration of the cicada life cycle via the Washington Post.

As I discussed the other day about other graphics, there are differences in how the two newspapers are presenting the same topic or subject matter. The New York Times piece concerns itself with the emergence over time of cicadas across the United States and links to historical articles about those events. Here, however, the Washington Post instead explains just how you get a seventeen-year period between emergences.

Additionally, the Washington Post maps near the end are not interactive as in the New York Times piece. But what this allows the Post to do is focus on those broods that impacted the Washington area instead of all those areas likely outside the Post’s core readership.
