Recharts plugins

Build and manage PortalJS data portals: recommend an architecture, scaffold a portal, add datasets (CSV/TSV/JSON/GeoJSON), create charts (recharts) and interactive maps (Leaflet), connect a CKAN backend, harvest datasets from open-data platforms, infer data schemas, audit data quality, and deploy to PortalJS Arc hosting.

Manage Treasure Studio workspaces: create and track documents, build interactive React dashboards with Recharts and Tailwind CSS, define grid dashboard and action report YAML schemas, create and validate scheduled tasks, perform web research, and build agentic Python workflows with Graflow.

Audit and improve visual design of websites, UIs, and documents against 11 research-backed principles including layout, typography, color, hierarchy, whitespace, and accessibility — with WCAG 2.2 AA checks, VisAWI scoring, and actionable fix suggestions.
