{"version":"1.0","type":"rich","title":"Global Poverty Levels Over Time","description":"This visualization combines a bubble map with a time-series histogram to show global patterns of missing migrants over time. The map projects circles sized by the total dead and missing using d3.geoNaturalEarth1 and d3.geoPath, while the histogram bins reported dates by month with d3.histogram and a brushX selection filters the map. Data comes from a CSV of Missing Migrants Global records, with country boundaries from World Atlas TopoJSON. React manages state and renders the SVG, with d3.scaleSqrt controlling circle radii.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9f0bd4cc2cd7472b86d20943101afa4e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
