{"version":"1.0","type":"rich","title":"Faking building height by using polygon size (CartoCSS)","description":"This example visualizes building footprints from OpenStreetMap by using polygon size to suggest height, with taller structures implied through larger, more prominent shapes. It applies CartoCSS styling to render the polygons with a semi-transparent black outline and a muted tan fill, while the `building-height` property references a `height` attribute from the data. The code relies on CartoCSS’s styling syntax to control line width, fill color, and opacity, but does not extrude actual 3D geometry; instead, it fakes verticality through 2D visual weight. The source data comes from an OSM export polygon layer.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4217963?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
