This example visualizes the structure of a hierarchical dataset as a force-directed network, where connected nodes form a branching tree-like layout. A first fork appears early in the graph, dividing the data into two distinct clusters. The visualization uses d3.forceSimulation to compute node positions and d3.forceLink for edge tension, rendering the nodes and links as SVG elements on a blank HTML canvas. The data source is embedded directly in the JavaScript code as an array of node and link objects.
