Dumbbell chart in React

Two dots joined by a bar per row, so the distance from before to after is the picture

type: 'dumbbell', x, start, end

This draws two dots joined by a bar per row, so the distance from a before value to an after value is the picture. It shows change per item at a glance, so the size of each move reads as the length of its bar.

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.
