{"version":"1.0","type":"rich","title":"Gist 4f403fa8b19f375639bc","description":"This example demonstrates a customized item model for a force-directed graph visualization, where a single node labeled “Bob” is rendered through a scaffolded class structure. The code defines `ItemModelScaffold2`, which inherits from `ItemModelScaffold` and overrides the `name` property to a static value of “Bob”, while leaving initialization and finalization methods as no-ops. The visualization uses a scaffolding registration API to bind this custom model to the base `ItemModel`, allowing the graph layout to treat Bob as a fixed, named entity without dynamic data updates. The rendering relies on the scaffold’s internal force simulation setup, though no explicit D3 calls appear in this snippet, focusing instead on model configuration.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4f403fa8b19f375639bc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
