It took a few years but npm is finally tracking download counts for scoped packages (here's the long running github issue if anyone's interested https://github.com/npm/download-counts/issues/23#issuecomment-294016319), we now have 1 month of stats, enough to make cool charts 😄
This site/tool was made in Vue btw (v1, haven't gotten around to migrating to v2 yet)
