Ask HN: Graph of Projects by License on GitHub? (MIT/BSD/GPL/etc.)

Has anyone plotted a graph of license usage over time on Github? I'd love to know for example whether GPL has gained or lost in popularity in the past five or ten years, whether MIT or BSD is more popular, and such.

For anyone searching on this, a couple days after I asked my question here the register published some data on this question [0]. They report copyleft licensing of open source projects fell from 60% in 2012 to 33% in 2019. The percentage of copyleft projects continues to fall the ratio appear to be leveling off towards perhaps 25% copyleft (GPL-like) and 75% permissive (MIT-like).
