Configure `key`, which can be any `string`, and register the plugin. This `key` will be used to lookup this chart throughout the app.
```js
import EventFlowChartPlugin from '@superset-ui/legacy-plugin-chart-event-flow';
new EventFlowChartPlugin()
.configure({ key: 'event-flow' })
.register();
```
Then use it via `SuperChart`. See [storybook](https://apache-superset.github.io/superset-ui-legacy/?selectedKind=plugin-chart-event-flow) for more details.
