Force Update Pattern
This example demonstrates the general update pattern applied to a force-directed graph, showing how nodes enter, update, and exit as the dataset changes every two seconds. Circle positions are governed by a `d3.forceSimulation` with charge, centering, and collision forces, while `d3.interval` triggers a restart with randomized letters and sizes. The code explicitly uses the join, exit, update, and enter phases with `d3.transition`, and renders SVG circles. Data is generated by shuffling the alphabet and randomly sampling names and sizes.
