{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"A streamgraph displays the total number of persons of concern (refugees, asylum-seekers, internally displaced persons, and others) over time, grouped by country of origin, with labels placed inside each area using the `d3-area-label` library. The visualization uses D3.js v4 with an SVG rendering, applying `d3.stack` with a wiggle offset and inside-out ordering to create the stacked areas. Data comes from UNHCR Population Statistics and is interpolated across years. The chart includes hover effects that darken each area and uses `d3.scaleTime` and `d3.scaleLinear` for axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f107a129a8f4825a9101a28171aef9b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
