Draw Io Diagram Generator

This is a proper mxGraph XML generator that creates draw.io files you can actually open without fixing broken references or missing geometry tags. It covers flowcharts, architecture diagrams, sequence diagrams, ER models, and UML classes, with templates for each and a validation script to catch malformed XML before you waste time debugging it. The workflow is structured: parse the request, pick a template or start fresh, plan the layout with real spacing numbers, generate cells with unique IDs and correct parent references, apply semantic color styles, and save. It handles the tedious parts like escaped labels, orthogonal edge routing, and swimlane containers. If you need diagrams in code reviews or documentation and want them version controlled instead of buried in some web app, this does the job.
