Background Row And Split By — Data grid with groups, categories, and a bar chart: Data grid of Sales, grouped by State, split by Sub-Category.

Data

Programmatic variations on the Superstore retail sales dataset, showing the flexibility of Perspective's configuration: the same table re-queried as data grids, pivot tables and charts by changing only the viewer's JSON config.

Loaded from /data/superstore.lz4.arrow as arrow into the perspective-server engine.

Configuration
