Differences between enterprise data visualization and data journalism

Toph Tucker used to make graphics for Bloomberg Businessweek. Now he does enterprise visualization for finance. He wrote about the major differences between the two jobs. On the iconic Bloomberg Terminal: There are more things in Bloomberg than are dreamt of in your meetings. This was not the consensus when I worked at Bloomberg, but I now believe the Terminal is incredibly well-designed. Folks reply, “I get that it’s useful,...

Does this chart tell the sordid tale of T1’s decline?

The Hustle has an interesting article on the demise of the T1 calculator, which is popular in business circles. The article uses this bar chart: From a Trifecta Checkup perspective, this is a Type DV chart. (See this guide to the Trifecta Checkup.) The chart addresses a nice question: is the T1 graphing calculator a victim of new technologies? The visual design is marred by the use of the calculator...

Pulling the multi-national story out, step by step

Reader Aleksander B. found this Economist chart difficult to understand. Given the chart title, the reader is looking for a story about multinationals producing lower return on equity than local firms. The first item displayed indicates that multinationals out-performed local firms in the technology sector. The pie charts on the right column provide additional information about the share of each sector by the type of firms. Is there a correlation...

Women workers taken for a loop or four

I was drawn to the following chart in Business Insider because of the calendar metaphor. (The accompanying article is here.) Sometimes, the calendar helps readers grasp concepts faster but I'm afraid the usage here slows us down. The underlying data consist of just four numbers: the wage gaps between race and gender in the U.S., considered simply from an aggregate median personal income perspective. The analyst adopts the median annual...

Too much of a good thing

Several of us discussed this data visualization over twitter last week. The dataviz by Aero Data Lab is called “A Bird’s Eye View of Pharmaceutical Research and Development”. There is a separate discussion on STAT News. Here is the top section of the chart: We faced a number of hurdles in understanding this chart as there is so much going on. The size of the shapes is perhaps the first...

Re-thinking a standard business chart of stock purchases and sales

Here is a typical business chart. A possible story here: institutional investors are generally buying AMD stock, except in Q3 2018. Let's give this chart a three-step treatment. STEP 1: The Basics Remove the data labels, which stand sideways awkwardly, and are redundant given the axis labels. If the audience includes people who want to take the underlying data, then supply a separate data table. It's easier to copy and...

Pay levels in the U.S.

The Wall Street Journal published a graphic showing the median pay levels at "most" public companies in the U.S. here. People who attended my dataviz seminar might recognize the similarity with the graphic showing internet download speeds by different broadband technologies. It's a clean, clear way of showing multiple comparisons on the same chart. You can see the distribution of pay levels of companies within each industry grouping, and the...

An exercise in decluttering

My friend Xan found the following chart by Pew hard to understand. Why is the chart so taxing to look at?  It's packing too much. I first notice the shaded areas. Shading usually signifies "look here". On this chart, the shading is highlighting the least important part of the data. Since the top line shows applicants and the bottom line admitted students, the shaded gap displays the rejections. The numbers...
