This example displays three labeled circles representing cars, trucks, and bikes, each positioned through a physics-based layout. The visualization uses D3.js v7 and a force simulation to arrange the nodes, with each circle corresponding to a data point in a hardcoded JavaScript array. The rendering is minimal, relying on SVG elements generated by D3’s data binding, though no interaction or animation is implemented beyond the initial simulation. The code structure is a static HTML page with inline scripting, demonstrating a basic force-directed graph setup.
