This example displays a small network of two main nodes and their connected child nodes, each labeled with a name and styled with distinct colors from a predefined palette. The visualization uses d3.forceSimulation with forceManyBody, forceLink, and forceCenter APIs to position the nodes, while SVG circles, lines, and text elements render the graph. Node data is generated in a separate JavaScript module, with forces applied through a tick event that updates the x and y coordinates of all elements automatically.
