Perspective › Examples
Y Area - Datetime Axis — Area chart. X is 'Order Date', bucketed by month. Y is sales. Each year is its own color and area.
Y Area chart of Sales, grouped by bucket("Order Date", 'M'), split by bucket("Order Date", 'Y'), with 2 computed expression columns.

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.
