{"version":"1.0","type":"rich","title":"Japan Country","description":"This map of Japan renders land areas as aquamarine shapes with black outlines, using a Mercator projection. The visualization uses topojson data fetched from a GitHub gist, with TopoJSON APIs (`topojson.presimplify`, `topojson.feature`) for simplification and conversion to GeoJSON. It applies D3’s `d3.geoTransform` to filter polygon details based on a threshold, which is adjustable via a range slider, and draws paths with `d3.geoPath` onto an SVG canvas. The map redraws dynamically when the slider changes or the window resizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/900fee9d8d444c33bdbe7fd4fe07adbf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
