For example, the Formula widget represents a single numerical statistic, such as an average or a count out of the column you define. And the Categories widget allows you to group and aggregate based on columns of your choice.
You can then turn those data models into interactive charts, filters and other HTML elements.

data models, such as yourSource.widgetSource.getCategories()
