This example visualizes the hierarchical structure of an XML Schema Definition (XSD) type, specifically the `TextureCoordinateType` complex type and its nested `IS` element. Built with D3.js, it uses `d3.forceSimulation` to position nodes in a force-directed graph, with links representing the `element` and `attribute` relationships from the XML. The visualization reads the gistfile1.txt source directly, parsing the XSD to extract the type hierarchy. Nodes are rendered as circles, and edges connect parent and child components, showing the schema’s logical layout. The code also references the `DefUseGroup` attribute group, indicating reuse of common definitions in the rendered graph.
