{"version":"1.0","type":"rich","title":"Circles on a Map of Slovakia","description":"A choropleth map of Slovakia encodes the number of apartments in apartment buildings per district as circles, scaled by a linear `d3.scaleLinear` and positioned at each district’s centroid via `d3.geoCentroid` and a `geoMercator` projection. Districts render as SVG paths from TopoJSON data, with hover highlighting, while a separate `sizeLegend` provides tick labels. The map supports zooming and panning through `d3.zoom` and uses `d3.tsv` and `d3.json` to load and join tabular census data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d907845850ce4c108f8f30680d7fb27e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
