Every control below re-queries a real SQLite database
(examples/data/sales.db) over the
canvasxpress-connectors /api/data contract: the
server runs a parameterized SELECT … GROUP BY product and the
bound panels refresh. The spec just declares the source URLs and the params
to pass — no client-side data.
Try: the Region dropdown (choices come from a
optionsFrom query) · the Search box (debounced,
filters products by name) · click a bar in “Revenue by region”
to cross-filter every panel to that region · watch the brief
Loading… overlay as each query runs.
