Much prettier. Could easily have larger pop-ups (entire point is to get information on elements, no?) <https://i.imgur.com/IVx5MY5.png>
Heck, even have a link to Wikipedia articles (why not?). You're obviously in the enjoyment of information sharing =D
You also have plenty of space for an example element (e.g. describe what each line represents e.g.g: density, atomic mass, proton/element #). The map's "key" if you will... not everybody knows these standardized chemnerd properties (you can then also remove the 120+ "RT" by simply placing in example element @STP, with a link to what that means, too).
Just feedback from a fellow dork am.chem.
