This gallery example presents a force-directed graph visualization of a network dataset. It uses the `d3.forceSimulation` API to compute physics-based node placement and `d3.geoPath` to render curved links between nodes. The visualization dynamically adjusts node positions in response to repulsive and attractive forces, with node color and size encoding additional data attributes. The underlying data is loaded from a JSON structure and rendered on an SVG canvas, providing an interactive exploration of network relationships.
