This interactive network visualization maps conceptual relationships between technology skills, with color-coded nodes grouped by category and labeled with skill names. Built with D3.js v7 and React, the force-directed layout uses `d3.forceSimulation` with link, many-body charge, center, and collision forces to position nodes. Users can drag nodes to reposition them, with the simulation responding in real time. The SVG rendering displays circles and text labels, with links drawn as gray lines. Data is hard-coded in the script, representing a small set of skills and their connections.
