-# React TypeScript DeveloperKit (Template)
+# @ciscode/ui-chart-kit
 
-Template repository for building reusable React TypeScript **npm libraries**
-(components + hooks + utilities).
+Typed React chart components (Bar, Line, Area) built on Chart.js.  
+Pass data and a theme — get a fully configured, responsive chart. No raw Chart.js options required.
 
-## What you get
+## Installation
 
-- ESM + CJS + Types build (tsup)
-- Vitest testing
-- ESLint + Prettier (flat config)
-- Changesets (manual release flow, no automation PR)
-- Husky (pre-commit + pre-push)
-- Enforced public API via `src/index.ts`
-- Dependency-free styling (Tailwind-compatible by convention only)
-- `react` and `react-dom` as peerDependencies
+```bash
+npm install @ciscode/ui-chart-kit
+```
 
-## Package structure
+### Peer dependencies
 
-- `src/components` – reusable UI components
-- `src/hooks` – reusable React hooks
-- `src/utils` – framework-agnostic utilities
-- `src/index.ts` – **only public API** (no deep imports allowed)
+| Package     | Version |
+| ----------- | ------- |
+| `react`     | ≥ 18    |
+| `react-dom` | ≥ 18    |
 
-Anything not exported from `src/index.ts` is considered private.
+`chart.js` and `react-chartjs-2` are bundled — you do **not** need to install them separately.
 
-## Scripts
+---
 
-- `npm run build` – build to `dist/` (tsup)
-- `npm test` – run tests (vitest)
-- `npm run typecheck` – TypeScript typecheck
-- `npm run lint` – ESLint
-- `npm run format` / `npm run format:write` – Prettier
-- `npx changeset` – create a changeset
+## Data types
 
-## Release flow (summary)
+### `ChartDataPoint`
 
-- Work on a `feature` branch from `develop`
-- Merge to `develop`
-- Add a changeset for user-facing changes: `npx changeset`
-- Promote `develop` → `master`
-- Tag `vX.Y.Z` to publish (npm OIDC)
+```ts
+interface ChartDataPoint {
+  label: string;
+  value: number;
+}
+```
 
-This repository is a **template**. Teams should clone it and focus only on
-library logic, not tooling or release mechanics.
+### `ChartDataset`
+
+```ts
+interface ChartDataset {
+  id: string;
+  label: string;
+  data: ChartDataPoint[];
+  color?: string; // hex color — falls back to theme.colors when omitted
+}
+```
+
+### `ChartTheme`
+
+```ts
+interface ChartTheme {
+  colors: string[]; // palette shared across datasets
+  fontFamily?: string;
+  fontSize?: number;
+  grid?: {
+    color?: string;
+    display?: boolean;
+  };
+  tooltip?: {
+    enabled?: boolean;
+    backgroundColor?: string;
+    titleColor?: string;
+    bodyColor?: string;
+  };
+  legend?: {
+    display?: boolean;
+    position?: 'top' | 'bottom' | 'left' | 'right';
+  };
+}
+```

+## Components
+
+### BarChart
+
+| Prop         | Type             | Default | Description                       |
+| ------------ | ---------------- | ------- | --------------------------------- |
+| `data`       | `ChartDataset[]` | —       | Datasets to render                |
+| `theme`      | `ChartTheme`     | —       | Theme (colors, fonts, grid, etc.) |
+| `height`     | `number`         | `300`   | Chart height in pixels            |
+| `stacked`    | `boolean`        | `false` | Stack bars on top of each other   |
+| `horizontal` | `boolean`        | `false` | Render horizontal bars            |
+
+```tsx
+import { BarChart } from '@ciscode/ui-chart-kit';
+import type { ChartDataset, ChartTheme } from '@ciscode/ui-chart-kit';
+
+const theme: ChartTheme = {
+  colors: ['#4F46E5', '#10B981', '#F59E0B'],
+  fontFamily: 'Inter, sans-serif',
+  fontSize: 12,
+  grid: { color: '#E5E7EB', display: true },
+  tooltip: { enabled: true, backgroundColor: '#1F2937' },
+  legend: { display: true, position: 'top' },
+};
+
+const datasets: ChartDataset[] = [
+  {
+    id: 'revenue',
+    label: 'Revenue',
+    data: [
+      { label: 'Q1', value: 120 },
+      { label: 'Q2', value: 180 },
+      { label: 'Q3', value: 150 },
+      { label: 'Q4', value: 210 },
+    ],
+  },
+];
+
+function App() {
+  return <BarChart data={datasets} theme={theme} height={400} stacked />;
+}
+```
+
+---
+
+### LineChart
+
+| Prop     | Type             | Default | Description                             |
+| -------- | ---------------- | ------- | --------------------------------------- |
+| `data`   | `ChartDataset[]` | —       | Datasets to render                      |
+| `theme`  | `ChartTheme`     | —       | Theme (colors, fonts, grid, etc.)       |
+| `height` | `number`         | `300`   | Chart height in pixels                  |
+| `smooth` | `boolean`        | `false` | Curved line interpolation (0.4 tension) |
+
+```tsx
+import { LineChart } from '@ciscode/ui-chart-kit';
+
+function App() {
+  return <LineChart data={datasets} theme={theme} smooth />;
+}
+```
+
+---
+
+### AreaChart
+
+| Prop      | Type             | Default | Description                             |
+| --------- | ---------------- | ------- | --------------------------------------- |
+| `data`    | `ChartDataset[]` | —       | Datasets to render                      |
+| `theme`   | `ChartTheme`     | —       | Theme (colors, fonts, grid, etc.)       |
+| `height`  | `number`         | `300`   | Chart height in pixels                  |
+| `smooth`  | `boolean`        | `false` | Curved line interpolation (0.4 tension) |
+| `stacked` | `boolean`        | `false` | Stack areas on top of each other        |
+
+Area fill uses the dataset color at 20 % opacity automatically.
+
+```tsx
+import { AreaChart } from '@ciscode/ui-chart-kit';
+
+function App() {
+  return <AreaChart data={datasets} theme={theme} stacked smooth />;
+}
+```
+

+
+## Design decisions
+
+- **No Chart.js passthrough.** Components expose a curated props API only.
+  Chart.js configuration is built internally via `buildChartConfig`.
+  This keeps the public surface small and prevents breaking changes
+  when Chart.js internals evolve.
+- **Colors cycle.** When there are more datasets than `theme.colors` entries,
+  colors wrap around automatically.
+- **Responsive by default.** Every chart renders inside a `div` with
+  `width: 100%` and the specified `height`.
