{"version":"1.0","type":"rich","title":"Persons of Concern StreamGraph by Origin","description":"This streamgraph visualization shows the total number of UNHCR persons of concern over time, grouped by country of origin, using d3.stack with the stackOffsetWiggle algorithm to create layered flowing areas. It includes interactive hover effects that highlight individual paths, with labels positioned via d3-area-label. The chart interpolates missing yearly data using d3.bisector and renders as SVG, with major and minor time axes. Data comes from UNHCR Population Statistics, filtered to exclude countries with relatively low counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/76631818791a48909d79d6562177e4dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
