{"version":"1.0","type":"rich","title":"Maptimeify a polygon in CartoCSS","description":"This visualization demonstrates how to apply a Maptime-themed rainbow outline to a specific building polygon using CartoCSS in TileMill. It shows a single OpenStreetMap feature (osm_id 260351411) styled with seven stacked line layers, each offset by two pixels and colored red, orange, yellow, green, blue, purple, plus a white halo. The CartoCSS snippet defines separate compositing layers (::red, ::orange, etc.) with line-width, line-color, and line-offset properties to create the striped effect. The example references tips from TileMill GitHub issue #2144 and credits AJ Ashton and Dane Springmeyer for the technique.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7e42180f6477dfd30a6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
