{"version":"1.0","type":"rich","title":"World Map","description":"This interactive world map visualizes population data by country for 2018, using color and size to distinguish between regions with and without reported figures. The visualization employs a natural Earth projection via `d3.geoPath` and `d3.geoNaturalEarth1`, with countries rendered as SVG paths. Population values are mapped to circle sizes using `d3.scaleSqrt`, and a size legend with tick marks displays the scale. Users can pan and zoom through `d3.zoom`, and hovering over a country reveals its population via a tooltip. Data comes from a CSV file joined to TopoJSON world atlas geometry.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/01dee2231b724d2f96c7abf5433715df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
