This plugin provides Calendar Heatmap for Superset.
### Usage
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 CalendarChartPlugin from '@superset-ui/legacy-plugin-chart-calendar';
new CalendarChartPlugin()
.configure({ key: 'calendar' })
.register();
```
Then use it via `SuperChart`. See [storybook](https://apache-superset.github.io/superset-ui-plugins/?selectedKind=plugin-chart-calendar) for more details.
