Sankey, chord and network in ESM

Relationships between categories

type, source, target, y

This shows relationships between categories as a sankey, a chord diagram and a network. It makes the connections in the data visible, how volume moves from one category to another, which rows and columns alone do not show.

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

<link rel="stylesheet" href="https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.min.css">

<div id="grid" style="height: 340px"></div>
<div id="chart" style="height: 320px"></div>

<script type="module">
  import { createGrid } from 'https://cdn.latticegrid.dev/lattice-grid@1.107.0/lattice-grid.esm.min.js';

  import { createChart } from '@toclocoinc/lattice-grid/modules/charts';

  const grid = createGrid(document.getElementById('grid'), {
    rowKey: 'id',
    columns: [
      { field: 'region', title: 'Region', filter: { type: 'set' } },
      { field: 'status', title: 'Status', filter: { type: 'set' } },
      { field: 'bandwidth', title: 'Bandwidth', type: 'number' },
      { field: 'utilisation', title: 'Utilisation', type: 'number', format: { decimals: 1, suffix: '%' } },
      { field: 'charge', title: 'Monthly charge', type: 'number',
        format: { style: 'currency', currency: 'GBP' }, total: 'sum' },
    ],
    rows,  // circuits: region, status, bandwidth, utilisation, charge
  });

  // A chart reads the grid's filtered rows and redraws when the grid changes.
  // Flow charts take source and target rather than x. sankey, chord and network
  // all read the same three fields.
  createChart({
    grid,
    container: document.getElementById('chart'),
    type: 'sankey',
    source: 'region',
    target: 'status',
    y: 'charge',
    title: 'Charge from region to status',
  });
