Revisiting global car sales

We looked at the following chart in the previous blog. The data concern the growth rates of car sales in different regions of the world over time. Here is a different visualization of the same data. Well, it's not quite the same data. I divided the global average growth rate by four to yield an approximation of the true global average. (The reason for this is explained in the other...

This Excel chart looks standard but gets everything wrong

The following CNBC chart (link) shows the trend of global car sales by region (or so we think). This type of chart is quite common in finance/business circles, and has the fingerprint of Excel. After examining it, I nominate it for the Hall of Shame. *** The chart has three major components vying for our attention: (1) the stacked columns, (2) the yellow line, and (3) the big red dashed...

This chart tells you how rich is rich – if you can read it

Via twitter, John B. sent me the following YouGov chart (link) that he finds difficult to read: The title is clear enough: the higher your income, the higher you set the bar. When one then moves from the title to the chart, one gets misdirected. The horizontal axis shows pound values, so the axis naturally maps to "the higher your income". But it doesn't. Those pound values are the "cutoff"...

Marketers want millennials to know they’re millennials

When I posted about the lack of a standard definition of "millennials", Dean Eckles tweeted about the arbitrary division of age into generational categories. His view is further reinforced by the following chart, courtesy of PewResearch by way of MarketingCharts.com. Pew asked people what generation they belong to. The amount of people who fail to place themselves in the right category is remarkable. One way to interpret this finding is...

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...
