{"version":"1.0","type":"rich","title":"Japan Map","description":"This map of Japan displays its prefectures as semi-transparent purple regions, with each area labeled by its name. The visualization uses `d3.geoMercator` for projection and `d3.geoPath` to render GeoJSON features from a TopoJSON source of Japanese towns. A sequential color scale, `interpolatePurples`, shades each state based on its position in the dataset, while text labels are positioned using `pathGen.centroid`. The map is rendered as SVG and supports zooming via D3’s `zoom` behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40a7d2f6d72e420b92091b41a64ac3e1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
