{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"This StreamGraph visualizes the number of persons of concern over time, grouped by country of origin, using data from UNHCR Population Statistics. A stack offset wiggle creates the flowing layers, with d3.area-label placing labels inside each region. The code uses d3.stack, d3.scaleTime, and d3.curveBasis to render the SVG, with interpolated values between annual data points. Major and minor axes display time, while hovering highlights individual country streams.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b097f159c62b4985bf3911ce010fab90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
