Widgets

To build a data widget with CARTO, you need:

• A data source: The data for your widget and layers. It contains the authentication, connection details and location for the data in your cloud data warehouse. Learn more about Data Sources.

  • Depending on the data source you're using, the widget will use server-side calculations (fully powered by your Data Warehouse) or client-side calculations (powered by the user's device after querying your Data Warehouse). Learn more about Server-side vs client-side.

• A data model:

  • getFormula

  • getCategories

  • getHistogram

  • getRange

  • getScatter

  • getTimeSeries

  • getTable

• Optionally, filters.

  • Column-based filters

  • Spatial filters

Additionally, you'll need:

• A UI of your choice: use a completely custom HTML component or integrate your favorite charting library. Many of our examples use Apache ECharts, but you can choose and customize your favorite library or component.
