{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"This streamgraph shows the total number of persons of concern—including refugees, asylum-seekers, and internally displaced people—grouped by country of origin, with data from UNHCR Population Statistics. Countries with low cumulative counts are excluded, and interactive hovering highlights a path in black. The visualization uses d3.v4 with d3.stack and is rendered as SVG, employing the d3-area-label library to position white labels. Year values are interpolated across a time axis with minor and major tick marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/daec96ed951f4617a40f0037e6d31c9f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
