Pie Chart Example

The data visualization api is a module that allows site builders to create, import & store data visualizations as entities and their data as standardized JSON. A user can then choose which installed data visualization library to use when rendering each data visualization entity.

All data is stored in a standardized format called Vizstruct. The spec for this specified JSON can be found here.

So far three adapters have been written to connect the Data Visualization API to individual rendering libraries. The adapter for Highcharts, JIT & jqPlot can be found here.


  • The ability to create and store Data Visualizations as entities.
  • The ability to choose which rendering library you want for individual visualizations.
  • Quick load times since the data is stored as JSON files and not database records.
  • Integration with the Color module for easy color palette selection.
  • The ability to place visualizations as blocks.
  • Import Vizstruct objects from file
  • Import data via CSV file
