{"version":"1.0","type":"rich","title":"Greenhouse gas emissions","description":"This visualization uses a small-multiples line chart to show annual greenhouse gas emissions from 1990 to 2012 for 15 countries, with the data sourced from a GitHub gist. The SVG-based animated chart is built with D3.v3, displaying each country's emission trend as a separate line. Countries are distinguished by color, and the animation reveals the time series progression, making it easy to compare changes over the two-decade span across nations.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-5572f0cb78cb45054525?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
