Unknown icon '{name}' on a network node; drew a plain disc instead. Register it with registerIcon or config.icons, or name a built-in.

What happened

The grid has an icon registry and it holds no icon under that name. The node drew as a plain disc, so the chart is complete but unlabelled by icon.

The fix

Register the icon before the chart draws, or use one of the built-in names.

The smallest fix

createGrid(el, { icons: { server: { viewBox: '0 0 24 24', paths: ['…'] } } });
