{"version":"1.0","type":"rich","title":"Tutorial Sunburst Datavisualisation","description":"This sunburst chart visualizes a categorical dataset of weapon types, showing hierarchical proportions through concentric arcs. The D3.js v4 code uses `d3.partition` and `d3.arc` with a `d3.hierarchy` structure, rendered as SVG paths from a sample dataset defining topics and sub-items. A dark background provides contrast for the color-coded segments. The example primarily demonstrates how to construct a sunburst layout programmatically rather than displaying the full provided data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/565d344748784467a319622b3a09b972?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
