-`chartgpu-react` is a thin React + TypeScript wrapper around [`@chartgpu/chartgpu`](https://www.npmjs.com/package/@chartgpu/chartgpu): lifecycle, resize, events, refs, and multi-chart GPU sharing in React. Core charting stays in ChartGPU (MIT commercial embed, zero npm runtime dependencies in core, WebGPU required, no WebGL fallback).
+- Async create/dispose lifecycle and debounced resize
+- Declarative event props and imperative `ChartGPUHandle` ref
+- Shared-device multi-chart via `useGPUContext` / `gpuContext`
+- Chart sync via `useConnectCharts` / `connectCharts`
 
-Use it when Chart.js, ECharts, or uPlot hit streaming or multi-panel walls. Commercial GPU seats often ship WebGL fallback and broader catalog; ChartGPU is the open WebGPU-only embed.
+ChartGPU renders with **WebGPU** (not Canvas2D or WebGL). There is **no WebGL/Canvas fallback**. Unsupported browsers must be gated by the host app.

-## Why chartgpu-react
+## Features
 
-| | |
-|---|---|
-| **React lifecycle** | Async create/dispose, debounced `ResizeObserver` sizing |
-| **Dense real-time jobs** | Multi-series streaming, multi-panel dashboards, finance, heatmaps (via core) |
-| **Shared-device multi-panel** | `useGPUContext` / `gpuContext` prop (recommended for ≥3 charts); `useConnectCharts` / `connectCharts` |
-| **Ring FIFO streaming** | `ref.appendData(..., { maxPoints })`; heatmap/surface stream APIs on core |
-| **Events and refs** | `onClick`, `onCrosshairMove`, `onZoomChange`, `onDataAppend`, `onDeviceLost`, …; `ChartGPUHandle` imperative API |
-| **MIT commercial embed** | MIT wrapper; core density stays free under MIT with no feature gates on FIFO, zoom, multi-chart, or finance series |
-| **WebGPU-only** | Same browser gate as core; no WebGL fallback |
+- **React lifecycle** — async create/dispose, StrictMode-safe, debounced `ResizeObserver` sizing
+- **Streaming** — `ref.appendData(..., { maxPoints })` FIFO ring; heatmap/surface stream APIs on core (`updateHeatmap`, `updateSurface3D`)
+- **Multi-chart** — `useGPUContext` + `gpuContext` prop (≥3 charts recommended); zoom sync via `useConnectCharts` / `connectCharts`
+- **Events and refs** — `onClick`, `onCrosshairMove`, `onZoomChange`, `onDataAppend`, `onDeviceLost`, …; full `ChartGPUHandle` imperative API
+- **External render mode** — app-owned rAF with `renderMode: 'external'`, `needsRender()`, `renderFrame()`
+- **Series via core** — line, area, bar, scatter, pie, candlestick, ohlc, heatmap, band, errorBar, impulse, step, stacked mountain, 3D (`pointCloud3d`, `surface3d`)
+- **MIT commercial embed** — wrapper and core density (FIFO, zoom, multi-chart, finance series) stay open under MIT
