Force Directed Graph with removable links

A force-directed graph shows relationships between entities, with nodes labeled by descriptions and links representing connections. Multiple links between the same pair of nodes are combined into a single red "multiLink" with a count, while individual links appear in steel blue. Users can click and drag circular handles along the edges to selectively remove red multi-link connections. Built with D3 v6, it uses `d3.forceSimulation` and `d3.forceLink` to position nodes, and loads data from JSON files defining nodes, links, and image icons.

Force Directed Graph with markers and selectable links

This example demonstrates a force-directed graph where multiple links between the same pair of nodes are visually distinguished using colored strokes and arrowhead markers indicating direction. The graph uses `d3.forceSimulation` to position nodes and `d3.forceLink` to manage connections, with selectable links rendered as SVG paths that trigger click events. Node data and link descriptions come from JSON files, and labels are positioned along curved edge paths using `textPath` elements.

Force Directed Graph with single links

This example shows a force-directed graph using D3.js v6, where nodes represent people and animals, linked by labeled relationships such as "owns" or "knows." The visualization uses the `d3.forceSimulation` API with a charge force, link force, and center force to position the nodes. Node images are rendered from a separate `images.json` file, and edges are drawn as paths with arrowheads and text labels along the curves. Users can drag nodes to fix their positions, and clicking a node toggles its selected state while restarting the simulation.
