Chart Canvas

About

Chart Canvas provides an interactive visualization dashboard designed for AI assistants, allowing users to generate charts, diagrams, and tables directly from their LLM conversations. It acts as an MCP server, displaying dynamic visualizations in real-time as you interact with models like Claude, ensuring data privacy by executing queries locally and never sending raw data to the LLM. Built with Vue 3, ECharts, and Mermaid, it offers a seamless way to transform raw data into rich visual insights.

Key Features

• Ensures data privacy by executing all queries locally via DuckDB, preventing sensitive data from leaving your machine or being sent to LLMs.
• Offers easy setup with a single command and integrates seamlessly with MCP clients for AI-driven visualization generation.
