Deformed Tree Map

Yesterday the BBC published an article about the success of the United Kingdom’s creative industry especially given the not-so-successful economy of the last few years. Unfortunately, the article included the tree map below.

The problems are a few. First, a tree map is usually looking at two variables. One is encoded through the size of the block and the other often its colour. Here, colour means nothing. So you are instead looking at only the size of the blocks. Basically, the same type of information that would be clearer to differentiate if this were a bar chart.

Second, a tree map has a hierarchy of placement. In other words, even if you cannot tell how much larger one block is from another—we all know we are not so great at comparing areas—you know which block is larger than the other by their arrangement in the map. Here we see no such hierarchy. The smallest block follows the largest block, which itself follows three other blocks.

Now that arrangement would be acceptable if the tree map were nested. That is to say if the different industries were grouped within like industries. Because then you would order those nested blocks. But that is also something not happening here.

All in all, this would have been a lot more effective of a chart if it had simply been made into a bar chart.

Squeezing You Into Your Airline Seat

Airlines want to make flights as profitable as possible. And that largely entails cramming as many people into those hollow cylinders called aircraft fuselages as possible. This is despite advice from Airbus, one of the world’s largest aircraft manufacturers to set a minimum seat width standard greater than US airlines are investigating. Thomson Reuters does a nice job illustrating the changes in this graphic.

Traffic Jam on the George Washington

A lot of people have been talking about Bridgegate, a scandal in New Jersey wherein the governor’s office allegedly abused its power to negatively impact the residents of Fort Lee, New Jersey. What actually happened for a few days this past fall? The Washington Post uses aerial photography and illustration to diagram the normal traffic flow and the flow during the traffic “study”.

Brand New Year, Same Old Politics

Today’s piece comes from this past weekend. The New York Times looked at how states fell on various politically sensitive issues, e.g. abortion and same-sex marriage, depending upon the political control of the executive and legislative functions of each state. In other words, which states have passed legislation to regulate abortion or same-sex marriage? States controlled by Democrats, or states controlled by Republicans?

I am not terribly keen on the clustered bubbles. Showing the population of each state could be handled better by different chart forms. But to a certain extent in this piece, the population figures are secondary to the aggregate of people living in blue or red states. And in that case, while you cannot easily visualise the number of people living in the aggregates, you can at least get a feel for which group is home to more people.

Coaching in Football (the American Kind)

This weekend we will have yet more football. My preferred team, the Philadelphia Eagles, is of course now out of contention. But more than likely, the coach’s job is secure for at least another year. As we have already seen, however, that cannot be said for other coaches. So the Washington Post looked at ownership’s role in the success of their respective team by the hiring and firing of coaches.

The Future of Data Visualisation

Okay, we have all watched enough science fiction to know that there is not one future, but multiple futures. All options existing as if taken in parallel universes. Today’s post is not about a specific graphic, but rather a short article in the New York Times examining data visualisation. Through the work of Eric Rodenbeck of Stamen Design, it looks at how we may need to change our current vocabulary, if you will. Naturally the article offers a counterpoint nearer the end about how older forms are still useful.

The Polar Vortex…Or Not

If you live in the United States, you probably have heard the term polar vortex by now. People have been using the term to describe the bitterly cold temperatures affecting the eastern two-thirds of the country. But the term polar vortex is a meteorological term that means a specific phenomenon. In other words, it’s more than a hashtag along the lines of snowmageddon. The Washington Post explains what the polar vortex is.

My caveat for this piece is that from my understanding, it’s not entirely correct. Or perhaps not detailed enough. In brief, we turn to the National Weather Service out of New York for a more technically correct, but more poorly designed graphic.

Poor type, poor colours, poor hierarchy. Those are abundantly clear, but the important part is that the NWS wants to correct many of the popular misconceptions. Somewhere between the well-intended but less-than-entirely-clear Post piece and the accurate-but-also-unclear National Weather Service piece is an opportunity to explain the concept to the public.

Holiday Tidings…of War

I’ve been away for over two weeks on holiday. So to spread good cheer to all, today I am sharing an image from a series of maps the BBC put together to try and explain the civil war in South Sudan.

Travelling for the World Cup

Well, travel for the teams, not you. It’s a big issue in Brazil because unlike the last couple of times, the teams need to travel big distances to reach the cities where they play their matches. Thankfully, to explain just how far some of these distances are for some of these teams, Quartz put together a nice article with quite a few graphics.

This graphic in particular juxtaposes the travels of the US team and the Argentinian team. Who do you think has it easier?
