{"version":"1.0","type":"rich","title":"activity 6 task 2 Q1","description":"This stacked bar chart shows the proportional CO2 emissions of four vehicle types—Sedan, SUV, Truck, and Motorcycle—split across four fuel categories: Petrol, Diesel, Electric, and Hybrid. Each horizontal bar is normalized to 100%, with colored segments representing fuel-type proportions. Built with D3 v7, the visualization uses `d3.stack()` to compute stacked series, `d3.scaleBand` for the vehicle-type axis, and `d3.scaleLinear` for the percentage scale. Data comes from a local CSV file, rendered as SVG with a color legend and percentage-formatted x-axis ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cf76f1247f7b41e2a45fd6648b268ba3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
