{"version":"1.0","type":"rich","title":"Something crazy","description":"This example displays a choropleth map of U.S. postal codes, where a randomly selected threshold dynamically recolors polygons based on their population totals. The visualization uses the CartoDB.js library to load a Leaflet map layer, then modifies its CartoCSS styling on each page load. A JavaScript function converts the current timestamp into an RGB color, which is applied to polygons exceeding a random population value, while all other areas retain a fixed pink fill. The underlying data comes from a CartoDB-hosted dataset of postal code boundaries.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-b65a3d8c8a1733ffbcbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
