Small multiples in React

One chart per category, on a shared scale

multiples: col

This draws one small chart per category on a shared scale, laid out as a grid of charts. It lets you compare many groups at once without overlaying them, so each category reads on its own but against the same yardstick.

Building…

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.

The configuration
