    Chart libraries and UI primitives by area

    Recharts vs ECharts, Progress, and totals helpers. Split from the former data_model inventory.

    Chart libraries and UI primitives by area

    For /analytics route status (discontinued chart UI), see charts-correlation-crosstab.md.

    Chart components / libraries

    From package.json:

    • recharts (^2.15.3)
    • echarts + echarts-for-react (wrapped by components/common/echarts/EChart.tsx)

    Representative components/ imports:

    • Line / bar / pie / area / radar: Recharts — e.g.
      components/fire-data/charts/CategoryTotalsChart.tsx
    • fire_data ECharts: components/fire-data/charts/echarts/ — drilldown (/simple), sankey, theme river, radar, treemap grid, heatmap, force graph, circle pack (/atlas + future routes); dashboard blocks: sunburst ↔ treemap morph via HierarchyMorphChart + hierarchy-morph.ts; bubble timeline via BubbleTimelineChart + bubble-timeline.ts (TimelineComponent + Scatter in EChart.tsx). Registry: registry.ts.
    • ECharts host (internal): components/common/echarts/EChart.tsx — not imported by routes; used inside product charts

    No Tremor in package.json.

    shadcn Progress

    Installed as Radix + local wrapper:

    components/ui/progress.tsx
    (re-exports Progress; uses @radix-ui/react-progress — also listed in package.json.)

    totals

    lib/utils/totals.ts exists; documents shared totals for live BRIS transform vs future getFireData + buildTotals.

    Maintenance

    When swapping chart stacks or adding a new visualization dependency, update this file and the analytics route doc if user-facing behavior changes.
