{"version":"1.0","type":"rich","title":"question paper model","description":"The visualization shows a hierarchical question paper model with \"questions\" branching into \"Long,\" \"short,\" and \"objective\" categories, which further split into \"5 marks,\" \"3 marks,\" and \"1 mark\" nodes. It uses a static tree layout via `d3.stratify` and `d3.tree`, rendering SVG circles and text labels. Links animate from source to target using `transition`, while circles fade in with a radial growth effect. Node colors change by depth through a custom `setGeneration` function, and the data is defined as an inline array of parent-child pairs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba73eb3099d242c1800b9193ab8bf33e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
