This network graph example demonstrates a simple, static layout of nodes and connections, presenting a minimalist visualization of relational data. The implementation uses a plain HTML page with CSS styling and relies on the React framework as its foundation. The code displays a large, centered message "Hello HTML!" rather than an actual graph, suggesting the visualization is a placeholder or starting point for building network diagrams. It does not utilize any specific data files or rendering libraries like d3.forceSimulation, instead serving as a basic template for users to expand upon.
