Transforming the data to fit the message

A short time ago, there were reports that some theme-park goers were not happy about the latest price hike by Disney. One of these report, from the Washington Post (link), showed a chart that was intended to convey how much Disney park prices have outpaced inflation. Here is the chart: I had a lot of trouble processing this chart. The two lines are labeled "original price" and "in 2014 dollars"....

Distorting geography to show train travels

Jan Willem Tulp visualized train travel times using distance and color as an indicator. His reasoning: When a train starts running from one station to the next station, conceptually, these two stations will temporarily be closer to each other. And that is exactly what this visualization shows: whenever a train moves to the next station — and only for as long as a train is moving — the origin station...

Made in France stereotypes

France is on my mind lately, as I prepare to bring my dataviz seminar to Lyon in a couple of weeks.  (You can still register for the free seminar here.) The following Made in France poster brings out all the stereotypes of the French. (You can download the original PDF here.) It's a sankey diagram with so many flows that it screams "it's complicated!" This is an example of a...

Made in France stereotypes

Kaiser Fung (JunkCharts, Principal Analytics Prep) shows how to use the Trifecta Checkup to identify weaknesses in data visualization, and also how to conceptualize good charts using the same framework. He uses an example inspired by a Made in France poster.

Education deserts: places without schools still serve pies and story time

I very much enjoyed reading The Chronicle's article on "education deserts" in the U.S., defined as places where there are no public colleges within reach of potential students. In particular, the data visualization deployed to illustrate the story is superb. For example, this map shows 1,500 colleges and their "catchment areas" defined as places within 60 minutes' drive. It does a great job walking through the logic of the analysis...

Visualizing the Thai cave rescue operation

The Thai cave rescue was a great story with a happy ending. It's also one that lends itself to visualization. A good visualization can explain the rescue operation more efficiently than mere words. A good visual should bring out the most salient features of the story, such as: Why the operation was so daunting? What were the tactics used to overcome those challenges? How long did it take? What were...

Several problems with stacked bar charts, as demonstrated by a Delta chart designer

In the Trifecta Checkup (link), I like to see the Question and the Visual work well together. Sometimes, you have a nice message but you just pick the wrong Visual. An example is the following stacked column chart, used in an investor presentation by Delta. From what I can tell, the five types of aircraft are divided into RJ (regional jet) and others (perhaps, larger jets). With each of those...

The personal data you generate when you book a flight

Every time we book a flight, a Passenger Name Record is generated and saved by an outdated system, which links to private travel data. Paz Pena, Leil-Zahra Mortada and Rose Regina Lawrence for the Tactical Technology Collective outline that data and describe the consequences of the system failing to keep data private. But although the PNR system was originally designed to facilitate the sharing of information rather than the protection...

A gem among the snowpack of Olympics data journalism

It's not often I come across a piece of data journalism that pleases me so much. Here it is, the "Happy 700" article by Washington Post is amazing.   When data journalism and dataviz are done right, the designers have made good decisions. Here are some of the key elements that make this article work: (1) Unique The topic is timely but timeliness heightens both the demand and supply of...
