-# Plotting MCP Server
+# 📊 Plotting MCP Server
 
-An MCP (Model Context Protocol) server that generates plots from CSV data, optimized for LibreChat integration.
+A MCP (Model Context Protocol) server that transforms CSV data into beautiful visualizations. Built with Python and optimized for seamless integration with AI assistants and chat applications.
 
-## Features
+## ✨ Features
 
-- Generate plots from CSV data strings
-- Support for multiple plot types: line, bar, pie
-- Returns base64-encoded PNG images compatible with LibreChat
+- **📈 Multiple Plot Types**: Create line charts, bar graphs, pie charts, and world maps
+- **🌍 Geographic Visualization**: Built-in support for plotting coordinate data on world maps using Cartopy
+- **🔧 Flexible Parameters**: Fine-tune your plots with JSON-based configuration options
+- **📱 Chat-Ready Output**: Returns base64-encoded PNG images perfect for AI chat interfaces
+- **⚡ Fast Processing**: Efficient CSV parsing and plot generation with pandas and matplotlib

 ### Tools
 
 #### `generate_plot`
-Generate a plot from CSV data.
+Transform your CSV data into stunning visualizations.
 
 **Parameters:**
 - `csv_data` (str): CSV data as a string
-- `plot_type` (str): Type of plot (line, bar, pie)
-- `**kwargs`: Additional plotting parameters.
-
-**Returns:** Base64 PNG image with data URL prefix
-
-## LibreChat Integration
+- `plot_type` (str): Plot type - `line`, `bar`, `pie`, or `worldmap`
+- `json_kwargs` (str): JSON string with plotting parameters for customization
+
+**Plotting Options:**
+- **Line/Bar Charts**: Use Seaborn parameters (`x`, `y`, `hue` for data mapping)
+- **World Maps**: Automatic coordinate detection (`lat`/`latitude`/`y` and `lon`/`longitude`/`x`)
+  - Customize with `s` (size), `c` (color), `alpha` (transparency), `marker` (style)
+- **Pie Charts**: Supports single column (value counts) or two columns (labels + values)
+
+**Returns:** Base64-encoded PNG image ready for display
+
+## 🤖 AI Assistant Integration
+
+Perfect for enhancing AI conversations with data visualization capabilities. The server returns plots as base64-encoded PNG images that display seamlessly in:
+
+- **LibreChat**: Direct integration for chat-based data analysis
+- **Claude Desktop**: Through `mcp-remote` command to transform from HTTP transport to stdio
+```json
+{
+  "mcpServers": {
+    "math": {
+      "command": "npx",
+      "args": [
+        "mcp-remote",
+        "http://localhost:9090/mcp"
+      ]
+    }
+  }
+}
+```
+- **Custom AI Applications**: Easy integration via MCP protocol
+- **Development Tools**: Compatible with any MCP-enabled environment
 
-This MCP server is designed to work with LibreChat. The generated images are returned as base64 PNG data that LibreChat can display directly.
+**Image Format**: High-quality PNG with configurable DPI and sizing
 
-Supported image format: PNG
