{"version":"1.0","type":"rich","title":"[SO 38995816] D3-Force updating parameters after initializing graph","description":"This interactive force-directed graph depicts character co-occurrence in Victor Hugo’s *Les Misérables*, using D3 v4’s `d3.forceSimulation` with link, charge, and centering forces. The novel feature is dynamic parameter updating: as the mouse moves over the SVG, the link distance is recalculated based on the cursor's distance from the center, and the simulation is restarted with an alpha of 1. This causes the graph to continuously re-layout, pulling characters closer or pushing them apart as the mouse moves. Nodes are draggable and colored by group, while link thickness encodes co-occurrence strength. The data, based on character co-appearances compiled by Donald Knuth, is rendered with SVG circles and lines.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-788f29ac122b463ecd340562da813e18?mode=embed\" width=\"960\" height=\"600\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":600,"cache_age":3600}
