This network visualization maps relationships between movie characters, with each character represented as a node and connections as links. Node color and shape encode role: blue stars for heroes, red triangles for villains, green circles for sidekicks, and orange squares for mentors. The animation relies on d3.forceSimulation with forceLink, forceManyBody, and forceCenter to compute layout, while d3.symbol applies the shape types. Labels are positioned manually, and the d3.drag interaction lets users reposition nodes. The dataset is hardcoded in the script, with force simulation ticks updating SVG line and path positions.
