ESM and Tree Shaking

The ESM build of the library supports tree shaking thus having no side effects. As a consequence the chart.js library won't be automatically manipulated nor new controllers automatically registered. One has to manually import and register them.

import { Chart } from 'chart.js';
import { HierarchicalScale } from 'chartjs-plugin-hierarchical';

// register scale in chart.js and ensure the defaults are set
Chart.register(HierarchicalScale);
