{"version":"1.0","type":"rich","title":"Project: Stacked Line","description":"This example visualizes music listening habits from a last.fm profile, showing stacked area charts of play counts per genre across the weeks of 2018. A color legend allows clicking to highlight or isolate a single genre, which re-renders the chart with smooth transitions. The visualization uses D3 v5 APIs including `d3.stack`, `d3.area`, `d3.scaleOrdinal`, and `d3.scaleLinear`, with SVG paths and animated transitions for interactivity. Data is loaded from a CSV and a nested JSON genre hierarchy, processed into weekly aggregates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/78db299646dc4dccb0c4fb731a74900e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
