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...

Playfulness in data visualization

The Newslab project takes aggregate data from Google's various services and finds imaginative ways to enliven the data. The Beautiful in English project makes a strong case for adding playfulness to your data visualization. The data came from Google Translate. The authors look at 10 languages, and the top 10 words users ask to translate from those languages into English. The first chart focuses on the most popular word for...

Lines, gridlines, reference lines, regression lines, the works

This post is part 2 of an appreciation of the chart project by Google Newslab, advised by Alberto Cairo, on the gender and racial diversity of the newsroom. Part 1 can be read here. In the previous discussion, I left out the following scatter bubble plot. This plot is available in two versions, one for gender and one for race. The key question being asked is whether the leadership in...

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...

Verging on trust

I’m not quite done with that Verge survey on social media popularity. Last time, I discussed one of the stacked bar charts about how much users like or dislike specific brands such as Facebook and Twitter. Today, I look at the very first chart in the article. This chart supposedly says users trust Amazon the most among those technology brands, just about the same level as customers trust their bank....

Using a bardot chart for survey data

Aleks J. wasn't amused by the graphs included in Verge's report about user attitudes toward the major Web brands such as Google, Facebook, and Twitter. Let's use this one as an example: Survey respondents are asked to rate how much they like or dislike the products and services from each of six companies, on a five-point scale. There is a sixth category for "No opinion/Don't use." In making this set...

Details, details, details: giving Zillow a pie treatment

This chart (shown right), published by Zillow in a report on housing in 2012, looks quite standard, apparently avoiding the worst of Excel defaults. In real estate, it’s all about location. In dataviz, it’s all about details. What are some details that I caught my eye on this chart? Readers have to get over the hurdle that “negative equity” is the same as “underwater homes.” This is not readily understood...

Speed demon quartered and shrunk

Reader Richard K. submitted a link to Microsoft Edge's website. This chart uses three speedometers to tell the story that Microsoft's Edge browser is faster than Chrome or Firefox. These speedometer charts are disguised racetrack charts. Read last week's post first if you haven't. Richard complained the visual design distorting the data. How the distortion entered the picture is a long story. Let's begin with an accurate representation of the...

Another simple Excel chart needs help

Twitter friend Jimmy A. asked if I can help Elon Musk make this chart "more readable". Let's start with a couple of things he did right. Placing SpaceX, his firm's data, at the bottom of the chart is perfect, as the bottom part of a stacked column chart is the only part that is immediately readable. Combining all of Europe into one category and Other U.S. into one group reduce...
