{"version":"1.0","type":"rich","title":"Fork of Japan Map","description":"This example displays a choropleth map of Japan’s prefectures, rendered as SVG paths with a uniform orange fill and white strokes. The code loads TopoJSON data twice via `d3.json` and uses `topojson.feature` to extract administrative boundaries. A `d3.geoMercator` projection with `d3.geoPath` draws the geography, while `d3.scaleOrdinal` and `schemeCategory10` are available for potential color encoding. The map supports pan and zoom through `d3.zoom`, transforming a grouped `<g>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/488a541357c8442d9b11baf2326c0692?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
