Sorting out what’s meaningful and what’s not

A few weeks ago, the New York Times Upshot team published a set of charts exploring the relationship between school quality, home prices and commute times in different regions of the country. The following is the chart for the New York/New Jersey region. (The article and complete data visualization is here.) This chart is primarily a scatter plot of home prices against school quality, which is represented by average test...

Attractive, interactive graphic challenges lazy readers

The New York Times spent a lot of effort making a nice interactive graphical feature to accompany their story about Uber's attempt to manipulate its drivers. The article is here. Below is a static screenshot of one of the graphics. The illustrative map at the bottom is exquisite. It has Uber cars driving around, it has passengers waiting at street corners, the cars pick up passengers, new passengers appear, etc....

Happy Valentine’s Day, America: Charting Our Declining Marriage Rate

It’s Valentine’s Day, a perfect time to note that the marriage rate in the United States has been on a steady decline for decades, save for a brief spike in 2012. So romantic. Here’s the rate per 1,000 people since 1997: You can also view that rate by state. What’s up with you, Hawaii? (I’ve excluded Nevada, which skewed the axes for all the small multiples because of its freewheeling...

Mapping the two Americas

If you type "two Americas map" into Google image search, you get the following top results: Designers overwhelmingly pick the choropleth map as the way to depitct the two nations. Now, look at these maps from the New York Times (link): and this: I believe the background is a relief map. Would like to see one where the color is based on the strength of support for Democrats or Republicans....

How will the Times show election results next week? Will they give us a cliffhanger?

I don't know for sure how the New York Times will present election results next week; it's going to be as hard to predict as the outcome of the election! The Times just published a wonderful article describing all the different ways election results have been displayed in the past. tldr; The designer has to make hard choices. Some graphics are better at one thing but worse at another. If...

Brexit, Bremain, the world did not end so dataviz people can throw shade and color

Catching a dose of Alberto Cairo the other day. He has a good post about various Brexit/Bremain maps. The story started with an editor of The Spectator, who went on twitter to make the claim that the map on the right is better than someone else's map on the left: There are two levels at which we should discuss these maps: the scaling of the data, and the mapping of colors....

NFL Geography: Where Were Professional Football Players Born?

Are states proportionally represented on the historical list of National Football League players? That’s the question I had four years ago when I posted two simple state-by-state maps summarizing players’ birth places. That post has been surprisingly popular, so I decided to remix the visualization a bit — replacing the old choropleth maps with tile grids. The latter can do a better job representing shaded values — in this case, the...

Raining, data art, if it ain’t broke

Via Twitter, reader Joe D. asked a few of us to comment on the SparkRadar graphic by WeatherSpark. At the time of writing, the picture for Baltimore is very pretty: The picture for New York is not as pretty but still intriguing. We are having a bout of summer and hence the white space (no precipitation): Interpreting this innovative chart is a tough task - this is a given with...

A multidimensional graphic that holds a number of surprises, via NYT

The New York Times has an eye-catching graphic illustrating the Amtrak crash last year near Philadelphia. The article is here. The various images associated with this article vary in the amount of contextual details offered to readers. This graphic provides an overview of the situation: Initially, I had a fair amount of trouble deciphering this chart. I was searching hard to find the contrast between the orange (labeled RECENT TRAINS)...

Delegate maps need a color treatment

This year's U.S. primary elections have been very entertaining. Delegate maps are a handy way to keep track of the horse race. They provide data to support (or refute) the narratives created by reporters who use words like "landslide", "commanding", etc. Here’s a delegate map used by the New York Times on the night of Mar 15th when Hillary Clinton won four out of five states, with the fifth (Missouri)...
