{"version":"1.0","type":"rich","title":"Regional breakdowns by month (CartoDB + D3)","description":"A grid of small pie charts displays regional unemployment data for each month, with one chart per region. Each pie is divided into equal slices for all twelve months, and the fill color of each slice encodes the monthly unemployment rate using a linear color scale. The visualization is built with D3 v3 for SVG rendering and pie layout, while CartoDB’s SQL API fetches the regional monthly values. A legend maps the color scale to numeric unemployment rates.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4602320?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
