Organization Network Graph
This example displays a network graph representing an organization, using a force-directed layout with D3's `d3.forceSimulation` to position nodes and links. The code includes a minimal HTML page with inline CSS and JavaScript, where the graph is rendered via SVG elements created through D3 selections. The visualization highlights the hierarchical relationships among organizational entities, though the current implementation only shows a placeholder "Hello HTML" message rather than a fully rendered graph.
