Force Directed Graph
This example shows a force-directed graph of programming language relationships, with nodes representing languages and curved links encoded with stroke style to show connection strength—green solid lines for stronger ties versus black dashed lines for weaker ones. Node size and blue color intensity reflect each language’s degree of connectivity. The visualization uses d3.forceSimulation with link, charge, center, and x/y forces, rendering nodes as SVG circles with drag interaction and tick-updated curved paths, while a small dataset is defined inline in the script.
