Uprading from 3.x

The component has been migrated to LitElement and uses TypeScript now. This migration introduced two breaking changes.

$3

The Polymer-specific selection-changed event commonly used for 2-way bindings has been removed.
There were previously two events for observing chart selection changes: google-chart-select and the Polymer-generated selection-changed.
For consistency with other events (e.g. google-chart-ready), we keep only google-chart-select.

Polymer components using this feature must be updated to explicitly name the selection event (details).
In the example below, note the addition of ::google-chart-select.

LitElement components using the selection-changed event must be updated in a similar fashion:

Its functionality can be imported from the loader.js module:

`javascript
import {dataTable, load} from '@google-web-components/google-chart/loader.js';
`

or you may instead choose to use google.visualization.ChartWrapper directly (example).
