Scatterplot matrix in ESM

Every pair of measures as its own small scatter, to spot which pairs move together

type: 'splom', columns

This draws every pair of measures as its own small scatter, arranged as a matrix. It lets you spot which pairs of columns move together across a dataset, so a relationship worth a closer look stands out.

Building…

Loading a live grid…

This is the ES module version. The grid is imported straight from a CDN as a module, the same configuration as the vanilla tab without a global script tag, so it drops into any bundler or a bare module script.

The configuration

    rows,  // instruments: symbol, desk, price, bid, ask, volume, notional
