{"version":"1.0","type":"rich","title":"Tree hierarchy","description":"This example visualizes a social network graph with six person nodes and seven friendship links using a force-directed layout. The D3.js force simulation (`d3.forceSimulation`) positions nodes in an SVG canvas, applying link, charge, and centering forces to arrange connections naturally. Each node is rendered as a colored circle with an adjacent text label, while lines represent relationships. Users can drag nodes via `d3.drag`, which temporarily fixes their positions during interaction, and the simulation updates positions on each tick event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ebac7712852b4086b3a1b12bd9b81d09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
