Apache ECharts is an open-source visualization library that offers twenty different types of charts and bundles several utility components to augment the charts. It prioritizes accessibility, is optimized for mobile devices, and can adequately display large quantities of data. The library has a large and active community behind it, ensuring continuous improvement. However, it lacks official libraries for various frontend web frameworks and mobile platforms, complicating integration. ECharts provides a more extensive list of chart types compared to other libraries like Chart.js, with greater customization capabilities. Integrating Cube with Apache ECharts in an Angular 13 app involves formatting query results into chart data, connecting the database to the Cube app, generating data schemas, building queries, and displaying the results using the ECharts library.
