xby-mathematical-visualization: JSXGraph-Based Mathematical Visualization MCP Service

`xby-mathematical-visualization` is an MCP server built on JSXGraph, designed to provide mathematical plotting capabilities for agents. It includes six core tools covering function plotting, parametric curves, geometric diagrams, vector fields, and linear system analysis, making it suitable for use in education, engineering, and science. When using it, numeric types (such as coordinate values) and string types (such as point names) must be strictly distinguished. It does not require heavyweight rendering libraries and enables intuitive, interactive mathematical visualization through a lightweight interface.
