{"version":"1.0","type":"rich","title":"Singapore topoJSON import","description":"This example displays the planning areas of Singapore as interactive SVG polygons, loaded from an external topoJSON file and rendered using D3’s `geoMercator` projection and `geoPath` generator. The map supports pan and zoom via the `d3.zoom` behavior with configurable scale and translate extents. Hovering over a region changes its fill color to red, and clicking logs the feature to the console. The visualization demonstrates importing topoJSON data with the `topojson.feature` helper, projecting geographic coordinates, and attaching zoom interactivity to a D3 selection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/652ec91808814385846b97cc8e9a288f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
