## Description

This MCP server provides AI assistants with the ability to generate ECharts visualizations as PNG images from JavaScript configuration objects. Built by w2xi using Node.js with the ECharts library and HTML5 Canvas for server-side rendering, it accepts chart dimensions and ECharts configuration strings, processes them through a secure function parser, and outputs image files to the user's Downloads directory or home folder. The implementation uses the Model Context Protocol SDK for tool registration and includes cross-platform directory writability checking, making it useful for creating data visualizations, generating charts for reports, and building AI assistants that need to produce visual representations of data without requiring a browser environment.
