{"version":"1.0","type":"rich","title":"Streamgraph","description":"This streamgraph shows how species abundance varies with latitude, using a stacked silhouette layout. The code loads CSV data and applies `d3.stack` with `d3.stackOffsetSilhouette` to create the layered structure, then renders it with `d3.area` and `d3.scaleLinear` axes. A `d3.scaleOrdinal` assigns colors from `d3.schemeDark2`. Interactive hover effects, managed via mouseover, mousemove, and mouseleave events, highlight a layer and display its group name in a tooltip. The visualization is built with D3 v6 and rendered as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4cd6048f599d4cf4bb8f515b763b1a07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
