{"version":"1.0","type":"rich","title":"Albers Equal Area | US Drought | April 2014","description":"A choropleth map of the United States shows drought severity from April 2014, using a dark USGS WELD tile layer as a base. CartoDB.js creates the map with Leaflet, transforming the drought polygons via ST_Translate and ST_Scale into a projected web mercator view. The choropleth colors range from yellow to dark red based on the drought magnitude (`dm`) attribute, with the CartoDB CSS template applying conditional polygon fills. The map centers on the lower 48 states at zoom level four.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-60359f268649d0615483?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
