McKinsey thinks the data world needs more dataviz talent

Note about last week: While not blogging, I delivered four lectures on three topics over five days: one on the use of data analytics in marketing for a marketing class at Temple; two on the interplay of analytics and data visualization, at Yeshiva and a JMP Webinar; and one on how to live during the Data Revolution at NYU. This week, I'm back at blogging. McKinsey publishes a report confirming...

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...

Big Macs in Switzerland are amazing, according to my friend

Note for those in or near Zurich: I'm giving a Keynote Speech tomorrow morning at the Swiss Statistics Meeting (link). Here is the abstract: The best and the worst of data visualization share something in common: these graphics provoke emotions. In this talk, I connect the emotional response of readers of data graphics to the design choices made by their creators. Using a plethora of examples, collected over a dozen...

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...

Is the chart answering your question? Excavating the excremental growth map

San Franciscans are fed up with excremental growth. Understandably. Here is how the Economist sees it - geographically speaking. *** In the Trifecta Checkup analysis, one of the questions to ask is "What does the visual say?" and with respect to the question being asked. The question is how much has the problem of human waste in SF grew from 2011 to 2017. What does the visual say? The number...

Two thousand five hundred ways to say the same thing

Wallethub published a credit card debt study, which includes the following map: Let's describe what's going on here. The map plots cities (N = 2,562) in the U.S. Each city is represented by a bubble. The color of the bubble ranges from purple to green, encoding the percentile ranking based on the amount of credit card debt that was paid down by consumers. Purple represents 1st percentile, the lowest amount...

This map steals story-telling from the designer

Stolen drugs is a problem at federal VA hospitals according to the following map. *** Let's evaluate this map from a Trifecta Checkup perspective. VISUAL - Pass by a whisker. The chosen visual form of a map is standard for geographic data although the map snatches story-telling from our claws, just as people steal drugs from hospitals. Looking at the map, it's not clear what the message is. Is there...
