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
