Time to breathe new life into my little YouTube channel, which I’m calling eagereyesTV. I’m doing so with the start of a new series I’m calling Chart Appreciation. Each episode will be on one particular visualization, news piece, or interactive. As the first one, I picked Hannah Fairfield’s Driving Safety, in Fits and Starts from 2012.

eagereyesTV: What Is Data? Part 2, Are Images Data?

eagereyesTV Episode 2: Unit Charts, Dot Plots, ISOTYPE, and What Makes Them Special
Charts usually show values as visual properties, like the length in a bar chart, the location in a scatterplot, the area in a bubble chart, etc. Unit charts show values as multiples instead. One famous example of these charts is called ISOTYPE, and you may have seen them in information graphics as well.
