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...

The Periodic Table, a challenge in information organization

Reader Chris P. points me to this article about the design of the Periodic Table. I then learned that 2019 is the “International Year of the Periodic Table,” according to the United Nations. Here is the canonical design of the Periodic Table that science students are familiar with. (Source: Wikipedia.) The Periodic Table is an exercise of information organization and display.

Visualizing the 80/20 rule, with the bar-density plot

The percentages vary, so long as the first number is small...

On the left side, with thicker pink bars that draw more attention, the design depicts the share of a particular GOP demographic segment that said they'd likely vote for a Trump challenger, according to a Morning Consult poll. This is the primary metric of interest,...

GDPR: justice for data visualization

Reader LG found the following chart, tweeted by @EU_Justice. This chart is a part of a larger infographic, which is found here. The following points out a few issues with this effort: The time axis is quite embarrassing. The first six months or so are squeezed into less than half the axis while the distance between Nov and Dec is not the same as that between Dec and Jan. So...
