Reading Log Graphs, Illustrated

This great, short video explains what we’re seeing on the graphs that take over our news feed these days. This is just about the math. The graphs use a logarithmic scale, and that is not something most people are used to reading. The animations in this video make this a lot easier to understand.

Another difference in these familiar graphs is that the time scale is based on the number of days that have passed, not on a calendar point. Again, the animation helps drive this point home.

(Note they promise to post this on YouTube April 28.)
