{"version":"1.0","type":"rich","title":"Activity6_Question2","description":"This stacked bar chart compares the proportional energy sources—coal, natural gas, nuclear, renewables, and other—across six countries using D3 v7’s `d3.stack`, `d3.scaleLinear`, and `d3.scaleBand`. Each bar segment is colored via a `d3.scaleOrdinal` color scale, and a hover tooltip reveals the exact percentage for each energy type. The SVG renders with custom axes and labels, reading the data from a CSV file that specifies each country’s energy mix as fractions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cec50417a63f4793b953bb8dd0535d04?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
