Digital revolution in China: two visual takes

The following map accompanied an article in the Economist about China's drive to create a "digital silkroad," roughly defined as making a Silicon Valley.  The two variables plotted are the wealth of each province (measured by GDP per capita) and the level of Internet penetration. The designer made the following choices: GDP per capita is presented with less precision than Internet penetration. The former is grouped into five large categories...

Well-structured, interactive graphic about newsrooms

Today, I take a detailed look at one of the pieces that came out of an amazing collaboration between Alberto Cairo, and Google's News Lab. The work on diversity in U.S. newsrooms is published here. Alberto's introduction to this piece is here. The project addresses two questions: (a) gender diversity (representation of women) in U.S. newsrooms and (b) racial diversity (representation of white vs. non-white) in U.S. newsrooms. One of...

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...

Steel tariffs, and my new dataviz seminar

I am developing a new seminar aimed at business professionals who want to improve their ability to communicate using charts. I want any guidance to be tool-agnostic, so that attendees can implement them using Excel if that’s their main charting software. Over the 12+ years that I’ve been blogging, certain ideas keep popping up; and I have collected these motifs and organized them for the seminar. This post is about...

The tech world in which everyone is below average

Laura pointed me to an infographic about tech worker salaries in major tech hubs (link). What's wrong with this map? The box "Global average" is doubly false. It is not global, and it is not the average! The only non-American cities included in this survey are Toronto, Paris and London. The only city with average salary above the "Global average" is San Francisco Bay Area. Since the Bay Area does...

When design goes awry

One can't accuse the following chart of lacking design. Strong is the evidence of departing from convention but the design decisions appear wayward. (The original link on Money here)   The donut chart (right) has nine sections. Eight of the sections (excepting A) have clearly all been bent out of shape. It turns out that section A does not have the right size either. The middle gray circle is not...

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...

Two nice examples of interactivity

Janie on Twitter pointed me to this South China Morning Post graphic showing off the mighty train line just launched between north China and London (!) Scrolling down the page simulates the train ride from origin to destination. Pictures of key regions are shown on the left column, as well as some statistics and other related information. The interactivity has a clear purpose: facilitating cross-reference between two chart forms. The...

Excel is the graveyard of charts, no!

It's true that Excel is responsible for large numbers of horrible charts. I just came across a typical example recently: This figure comes from Edward Wolff's 2012 paper, "The Asset Price Meltdown and the Wealth of the Middle Class." It's got all the hallmarks of Excel defaults. It's not a pleasing object to look at. However, it's also true that Excel can be used to make nice charts. Here is...

Report from the NBA Hackathon 2017

Yesterday, I had the honor of being one of the judges at the NBA Hackathon. This is the second edition of the Hackathon, organized by the NBA League Office's analytics department in New York, led by Jason Rosenfeld, pictured here speaking to the crowd: The event was a huge draw - lots of mostly young basketball enthusiasts testing their hands at manipulating and analyzing data to solve interesting problems. I...
