{"version":"1.0","type":"rich","title":"RT05_Network Graph","description":"This interactive network graph visualizes the relationships between COVID-19, its variants, and associated symptoms. Nodes representing concepts like \"Delta Variant\" and \"Fever\" are positioned using a force-directed layout, with connecting lines (links) whose thickness corresponds to a weight value. The visualization uses the D3.js v4 library, specifically leveraging the `d3.forceSimulation` API for physics-based node placement and the `d3.json` method to load hierarchical data from a local `data.json` file. Rendered as an SVG with custom styling, the graph allows users to drag nodes, revealing the interconnected structure of the topic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0bf61438fee6417e9f296dfb8ae02265?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
