{"version":"1.0","type":"rich","title":"L","description":"A choropleth map of U.S. census block groups colors each polygon by a seven-step color ramp based on the `median_rent_moe` column, overlaid on a dark CartoDB basemap. The example generates a static 500×200 pixel image centered at latitude 40, longitude -100, using the CartoDB SQL API to compute Jenks natural breaks for classification. The `CartoImage` class builds a CartoCSS style, posts a map configuration to the CartoDB static map endpoint, and returns the resulting PNG URL.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-7b6be7f87d1af6ac53a3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
