This example demonstrates a component-drilling interaction where a navigation bar and an address book are linked through a force-directed graph. It uses d3.forceSimulation to position and animate the connected nodes, with each node representing a UI component. The visualization shows how selecting a component in the navigation bar drills down to highlight its corresponding details in the address book. The code relies on D3’s drag and click handlers to update the graph’s state, while the address book and navigation bar are rendered as HTML elements that respond to the simulation’s data bindings.
