A force-directed network graph visualizes career progression paths across three distinct fields: software development, design, and healthcare. Pink circular nodes represent job titles, with gray lines showing progression links, including one cross-field connection from Data Scientist to UI/UX Designer. The layout uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to position nodes dynamically. Users can drag any node, which triggers `d3.drag` events that adjust the simulation's alpha target and apply temporary position forces during interaction.
