{"version":"1.0","type":"rich","title":"World Bank Climate CO2 Emissions (per capita) D3 + CartoDB","description":"A grid of small SVG donut charts displays per-capita CO2 emissions for countries from 1979 to 2009, with each ring segment representing a year and colored by emission value via a linear scale from white to red. The visualization loads data from the CartoDB SQL API using a JSON query, and D3.js v3 builds the pie layout and arcs. Hovering highlights a segment, and tooltips show the year and value. A legend maps the color scale to emission levels, while the underlying dataset comes from the World Bank indicator.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-4615355?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
