{"version":"1.0","type":"rich","title":"Streamgraph 2.0","description":"This streamgraph displays changes in Dutch societal indicators from 2000 to 2018, including happiness, depression-related deaths, suicides, and bachelor’s degree graduates. The visualization uses a silhouette offset to center the stacked areas around a central axis, with each colored layer representing a different metric. Built with D3 v4, the example loads data from a CSV file and uses `d3.stack` with `d3.stackOffsetSilhouette` to compute layer positions, while `d3.area` generates the SVG paths. An ordinal color scale applies the `d3.schemeDark2` palette, and interactive tooltips reveal the layer name on mouse hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e81fbb8eab9a4edfa092e5fca451388d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
