{"version":"1.0","type":"rich","title":"ice8_task2","description":"A dark-themed visualization gallery presents two interactive D3 v7 diagrams: a hierarchical tree of programming languages and a force-directed network of authors and papers. The tree uses `d3.hierarchy` and `d3.tree` to arrange nodes by depth, with shapes varying by level and colors by layer, while hover highlights links. The network uses `d3.forceSimulation` with link, charge, and center forces, representing authors as circles and papers as squares, with drag repositioning and tooltips. Both render as SVG with original data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ccabef213f14799a9774d49b5c609f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
