{"version":"1.0","type":"rich","title":"Fork of Japan Map","description":"This example presents a zoomable choropleth map of Japan’s administrative regions, rendered as SVG paths filled with distinct colors from a categorical scale. Using D3 v5 and d3-geo-projection, it applies a Mercator projection clipped to the viewport, with pan and zoom enabled via d3.zoom. Geographic boundaries come from TopoJSON data (JPN_adm1), processed with topojson.feature and drawn using d3.geoPath. The map highlights each prefecture uniformly, with white strokes separating regions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e768552e02a941fe860d9080387d6e96?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
