+# Charta — Chart Generator
+
+Generate presentation-ready charts directly from Cursor. Waterfall, Mekko/Marimekko, bridge, bar, grouped bar, stacked bar, scatter, line, area, combo, funnel, gantt, heatmap, and bubble charts — all as SVG or PNG.
+
+## What it does
+
+The Charta MCP server exposes two tools:
+
+- **`generate_chart`** — Generate a chart from your data. Returns SVG (or PNG if you ask). No setup, no libraries — just describe the chart and pass the data.
+- **`save_chart`** — Save a previously generated chart to disk.
+
+## Example
+
+```
+Generate a waterfall chart showing Q1 revenue bridge:
+Starting: 100, New Business: +45, Churn: -12, Expansion: +23, Ending: 156
+```
+
+Cursor calls `generate_chart` and returns a publication-quality SVG you can drop straight into a slide deck or doc.
+
+## Install
+
+This plugin auto-configures the MCP server. No additional steps required.
+
+Manual config (if needed):
+
+```json
+{
+  "mcpServers": {
+    "charta": {
+      "command": "npx",
+      "args": ["-y", "@charta/mcp"]
+    }
+  }
+}
+```
