{"version":"1.0","type":"rich","title":"Japan Map","description":"This visualization displays a choropleth map of Japan’s administrative regions, with each prefecture filled in a uniform red color and separated by white borders. The map uses an equirectangular-like Mercator projection via `d3.geoMercator` and renders geographic features with `d3.geoPath`. The code loads TopoJSON data for both states and districts, then applies `d3.scaleOrdinal` with a category color scheme, though only the state layer is drawn. Interactive zoom and pan are supported through D3’s `zoom` behavior, which transforms the SVG group containing the map paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e16fe3a12b5247c7a2499e58b61c152c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
