+
+This plugin provides Word Cloud 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 WordCloudChartPlugin from '@superset-ui/legacy-plugin-chart-word-cloud';
+
+new WordCloudChartPlugin()
+  .configure({ key: 'word-cloud' })
+  .register();
+```
+
+Then use it via `SuperChart`. See [storybook](https://apache-superset.github.io/superset-ui-plugins/?selectedKind=plugin-chart-word-cloud) for more details.
+
+```js
+<SuperChart
+  chartType="word-cloud"
+  width={600}
+  height={600}
+  formData={...}
+  queryData={{
+    data: {...},
+  }}
+/>
+```
