This component is new and has not yet undergone full testing. The API may change before it is considered stable, and it may not function as expected when not using the Core Design System (CDS) theme.

Chart component built on Apache ECharts, an open-source charting library.

Unlike uwc-chart, which is built on the commercially-licensed Highcharts library and requires a Temenos OEM licence limited to specific named products, uwc-chart-open has no licensing restriction — it can be used on internal projects and any other project not specifically covered by the Highcharts OEM licence.

Split config (structure) from data (series) just like uwc-chart does for Highcharts. Changing `config` triggers a full option reset (notMerge); changing only `data` merges the new series without touching axes, titles, or other config.

For more complex chart types than shown below — stacked/mixed series, gauges, sankey diagrams, calendar heatmaps, 3D charts and more — see the official ECharts examples gallery. Any option object from the gallery can be passed directly to the `config` property.
