Soooo cool ! I’m intrigued by the heavy planets orbiting lightweight stars, ie the ones on the right hand side of the graph colored blue. If I understand correctly, the color scale is in solar masses? but what is the horizontal unit?

Oh wait, it’s a bot repost. Does the bot post a link to here on the original Reddit thread by any chance?

Ok I got my answer. from the OT :

The axes are using Earth masses and Earth radii, so Earth would be at 100 or 1 Earth mass and Earth radius, towards the bottom left tail of the population. Similarly, the stellar mass is given relative to the Sun, so 1.0 solar radius is around the medium orange color.
