Ridgeline: JavaScript Data Grid Demo

A distribution per category, stacked on a shared scale so the shapes line up to compare

type: 'ridgeline', x, y

This draws a distribution per category, stacked on a shared scale so the shapes line up. It lets you compare how the spread of a value differs across many groups at once, shape against shape.
