{"version":"1.0","type":"rich","title":"Hello HTML","description":"This example shows a force-directed network graph of university courses, where nodes represent courses and links show associations between them with labels describing support and confidence values. The visualization uses D3 v3’s `d3.layout.force` for layout and computes node positions and link paths, which are rendered as SVG curves with arrowheads via a custom marker. Course names are displayed within the network, and link styling and text are set using SVG `path` and `textPath` elements. The data is hardcoded in a JavaScript array, and the page runs as a bare HTML document with React integration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9adf5483085e4274b411af7e8edeac83?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
