{"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 persons—grouped by country of origin over time, drawing on UNHCR population statistics. The visualization uses d3.stack with a wiggle offset to create the layered streams, and d3.area-label to place labels inside the curves. Data is interpolated across years to produce continuous paths, with hover effects altering fill opacity. Excluding low-count countries, the chart renders as an SVG with a time-based x-axis and a stacked area layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e0f81b462a7843bdbcde9cb0801c82d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
