{"version":"1.0","type":"rich","title":"Fork of Circles with D3","description":"This example presents two related visualizations: a force-directed network graph and a hierarchical family tree, both built with D3.js v7 and rendered as SVG. The network graph uses `d3.forceSimulation` with link, charge, and centering forces to position named nodes connected by red links, while labels update on each tick. The family tree applies the `d3.tree` layout to structural parent-child data. Both charts share a consistent dark red and green color scheme, with data hardcoded as JavaScript arrays.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/784f998b73b4430bb75f8d8d3895f3e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
