Just a note that I’ve decided to step back from metrics graphics maintenance for the time being, which means that the project is essentially unowned. This has sort of been the case for a while, but I figured I should probably make it official.
If you follow the link to the metrics graphics repository, you’ll note that the version has been bumped to “3.0-alpha3”. I was this close to making one last new release this afternoon but decided I didn’t want to potentially break existing users who were fine using the last “official” version (v3.0 bumps the version of d3 used to “5”, among other breaking changes). I’d encourage people who want to continue using the library to make a fork and publish a copy under their user or organization name on npm.
