PortalJS — Add Chart

Overview

Add a visualization to a dataset's showcase in a PortalJS portal. The skill installs recharts (added directly — never @portaljs/components), writes a reusable client-side Chart component into components/, and renders a <Chart /> into the Views section of the showcase route pages/[owner]/[slug].tsx for one chosen dataset. The chart reads the same /public/data/<file> the showcase <Table /> already uses, so no data is duplicated. Five chart types are supported: line, bar, area, pie, and scatter.

Prerequisites

• A scaffolded PortalJS portal (see portaljs-new-portal).
• The target dataset already registered in datasets.json (see portaljs-add-dataset).
• components/ui/parseCsv.ts present (ships with the template).
• Node 18+ and npm available in the portal directory.
