This interactive network graph visualizes the connections among programming languages, project categories (Web Dev, AI/ML, Games), and the central "Programming" hub. The SVG layout is computed by d3.forceSimulation with d3.forceLink for link constraints, d3.forceManyBody for repulsion, and d3.forceCenter to keep nodes centered. Nodes are colored by group using d3.scaleOrdinal with d3.schemeCategory10, and the drag API binds user interaction to pin dragged nodes.
