{"version":"1.0","type":"rich","title":"A8 - Node-link diagram with force-directed layout","description":"This example displays a food network as a node-link diagram with a force-directed layout. It uses D3.js v7's `d3.forceSimulation` with link, charge, and center forces to position nodes and edges. Node interactions include hover effects that enlarge circles and reveal a tooltip with the node ID. Data is loaded from a CSV file via `d3.csv`, and the visualization is rendered as animated SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f24640cd0b514a45a59b9f92e3a5cf4c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
