A ternary plot of citrus geneology

Seems to be missing the Etrog? https://en.wikipedia.org/wiki/Citrus_taxonomy#Citrons

Also, the "click to show search results" is cool but fails for "Arizona Citron" in obvious ways.

A Persian lime is a cross between a Key lime and a lemon? I never would have guessed that, that's really interesting.

This is cool! I do wish I could search for a specific citrus by name.
