{"version":"1.0","type":"rich","title":"Streamgraph 1.0","description":"A streamgraph displays changes in five data series from 1996 to 2018, including happiness scores, mood disorder diagnoses, and suicide-related metrics. Using d3.stack with stackOffsetSilhouette, the code layers filled areas symmetrically around a central axis, with d3.scaleOrdinal and d3.schemeDark2 assigning colors. The SVG rendering includes a gridline-based x-axis, and interactive hover effects dim other areas while tooltips identify the selected series. Data comes from a CSV file loaded via d3.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/312c1030954a4a5bae87042cf46ecc7d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
