Charting all the major California wildfires since 2000

Based on data from CAL FIRE, Erin Ross, for Axios, plotted California wildfires that spanned at least 300 acres since 2000. Each triangle represents a fire, where the height represents acres burned (width is the same for all triangles) and color represents duration. The fires appear to be burning hotter and longer.

I wonder if it’s worth doubling up on the triangle encoding by using width to represent duration, similar to the Washington Post graphic made during the elections.
