Ridgeline in React

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.

Loading a live grid…

This is the React version. The grid mounts through the createLatticeGrid adapter, which takes its configuration as ordinary props and hands back the live grid through a ref. The grid below is the same one every other tab runs.
