This visualization shows a project schedule as a network of activities and their dependencies, with each circular node representing a task and light-blue links representing finish-to-start relationships. The data comes from the RanGen project management dataset, stored as JSON. Using d3.forceSimulation with forceX, forceY, forceCollide, and forceManyBody forces, the code positions nodes on a canvas and redraws the network on every simulation tick via the Canvas API.
