{"version":"1.0","type":"rich","title":"activity6_question2.1","description":"This stacked bar chart displays car specifications—horsepower, torque, and highway mpg—for manufacturers like Scion, Kia, and Ferrari. Each horizontal bar uses segments scaled by value, with a legend mapping colors to specifications. The visualization is built with D3 v7, using d3.stack() to aggregate data and d3.scaleOrdinal() for colors. Hovering over segments dims them and a tooltip shows exact values. Data comes from the included data.csv file and renders as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/394248f3feeb4a01a30c624d5f82a608?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
