/**
 * Description of import into Moodle:
 *
 * - Download Chartjs source code (zip) file from https://github.com/chartjs/Chart.js/releases/latest.
 * - You must build Chart.js to generate the dist files (https://www.chartjs.org/docs/latest/developers/contributing.html#building-and-testing).
 *   Chart.js will generate a new file dist/chart.umd.js with minified format, in order to avoid the minification
 *   we need to modify rollup.config.js, find below code in the file:
 *   ```
 *   1. // UMD build
 *   2. // dist/chart.umd.js
 *   3. {
 *   4.     input: 'src/index.umd.ts',
 *   5.     plugins: plugins(true),
 *   6.     output: {
 *   7.       ...
 *   8.     },
 *   9. },
 *   ```
 *
 *   Change line 5 into:
 *   ```
 *   plugins: plugins(),
 *   ```
 *
 *   Save the file and run build script again.
 *
 * - Copy /dist/chart.umd.js content to lib/amd/src/chartjs-lazy.js.
 * - Remove below line in the lib/amd/src/chartjs-lazy.js:
 *   ```
 *   //# sourceMappingURL=chart.umd.js.map
 *   ```
 * - Convert line endings to LF-Unix format.
 * - Change the version number and the copyright year at the file header block.
 * - Keep these instructions in the file.
 * - Visit lib/tests/other/chartjstestpage.php to see if the library still works after the update.
