{"version":"1.0","type":"rich","title":"Fork of Persons of Concern StreamGraph by Origin","description":"This streamgraph visualizes the total number of persons of concern—including refugees, asylum-seekers, and internally displaced persons—grouped by country of origin, from 1951 to 2015. The chart uses a wiggle offset to show changes in each country’s contribution over time, with labels positioned by the `d3-area-label` library. Data comes from UNHCR Population Statistics, filtered to exclude countries with low total counts. The SVG rendering uses D3 v4 APIs including `d3.stack`, `d3.stackOffsetWiggle`, and interactive hover effects that highlight individual paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/418df9a2a16640c5a294fee2693ad3aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
