The graphical visualization skills of the New York Times leave me envious. For that reason, a plot in the sports section on August 12, 2015 regarding aces by male tennis players caught my eye. Not having the data available to the Times, I sort-of re-created the plot below. In the same style, mine shows how […]

Let’s take a look at a plot from a survey conducted by DigitalWarRoom, its “2015 Ediscovery IQ Meter.” On page 12 of the report, which was published in July 2105, there is a plot that looks quite similar to the plot below.

We revisit the same Winston & Strawn plot which appears as the plot as it was in the most recent post in its improved re-incarnation. Now, let’s take up four more observations.   The thick black line on the vertical y-axis adds nothing: It is an example of what is referred to as “chart junk”, […]

Another aspect of the plot that has been discussed previously [Click here for the latest post in this series] should be called out. Whoever prepared the plot chose to color differently each bar of the three risks most often selected. The blue bar represents “geographic locations in which the company operates”, a sort-of red bar […]
