What happened

The grid has an icon registry and it holds no icon under that name. A network node drew as a plain disc and a chart image marker kept the default marker, so the chart is complete but lacks the 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: ['…'] } } });
