{"version":"1.0","type":"rich","title":"Circles on a Map of Slovakia","description":"A choropleth map of Slovakia displays districts colored by municipal boundaries, overlaid with scaled circles indicating the number of apartments in residential buildings per district. The visualization uses D3 v5 with a Mercator projection and `geoPath` to render the TopoJSON geometry, while circle radii are sized via a linear `scaleLinear`. District data from a TSV file is joined with geometric features, and a `sizeLegend` displays the population scale. Pan and zoom interactions are enabled through a D3 zoom behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7165742431ca47799e4cf6682daad98e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
