# Project Boundary (Gantt example)

> WestCoast Charts 1.1.5, release, public Core release, on npm. HTML: https://westcoast-charts.com/gallery/gantt/project-boundary/ · Index for agents: https://westcoast-charts.com/llms.txt

plotOptions.gantt.boundary draws the project start and deadline as labelled lines and shades the time outside them. Tasks that cross a boundary get a warning mark, a tooltip line and a screen-reader note; api().outOfBounds() lists them.

- Chart type: `gantt` (Gantt)
- Collection: Gantt · Gantt
- Raw configuration: https://westcoast-charts.com/gallery-src/gantt/project-boundary.js
- Standalone example: https://westcoast-charts.com/embed/samples/wcc/gallery/premium/gantt/project-boundary.html

## Verify

- Text check (Library 1.1.5): load `west-coast-charts/agent/describe` and call `chart.describe({ format: "json" })` for the actual drawn state. The live reader is on this example’s HTML page.
- Command line (Public agent tools 0.2.3, tested with Library 1.1.5; available from the versioned GitHub release and npm, https://westcoast-charts.com/docs/cli/index.md): `wcc chart export gantt-project-boundary.json --out gantt-project-boundary.svg --with-table` (save the options above as JSON first)
