{"version":"1.0","type":"rich","title":"Video Dependency Graph","description":"This example displays the dependency structure of a video course as a static graph, listing 14 tutorial nodes with titles and durations, though the link array is initially empty. The visualization loads the JSON dataset and renders it in a `<pre>` element by serializing the data with `JSON.stringify(data, null, 2)`. Using D3 v5's `json()` function and the `select()` API, the code demonstrates a minimal approach to fetching and displaying raw hierarchical data without any interactive or force-directed layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/70c01de344264db49c06281818a21950?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
