{"version":"1.0","type":"rich","title":"Sequences sunburst","description":"This sunburst chart visualizes the hierarchical distribution of user navigation sequences on a metagenomics site, showing the proportion of each path from the root. Hovering over a segment highlights its ancestor chain and displays a breadcrumb trail with the exact percentage of total visits. The code uses `d3.partition` and `d3.arc` to compute and draw the arcs, while `d3.hierarchy` and `d3.csvParseRows` process the input data. Mouseover events trigger opacity transitions and breadcrumb updates, with colors mapped to distinct step names.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8888847b395549e48bc33ccba9b1f082?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
