Alluvial flow in React

Follow a measure as it flows from one category into another, ribbon by ribbon

type: 'alluvial', source, target, value

This follows a measure as it flows from one category into another, ribbon by ribbon. It shows how a total redistributes between two groupings, so a shift in the mix reads as the width of each ribbon.

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.
