{"version":"1.0","type":"rich","title":"Activity6_Task2","description":"This stacked bar chart compares horsepower, torque, and highway MPG across car manufacturers, showing how each performance metric contributes to a total value per make. The visualization uses D3.js v7 to create SVG bar segments via the `d3.stack()` function, with a color scale distinguishing metrics. Hovering over a bar segment triggers a tooltip displaying the exact metric value, while axis labels and a legend clarify the categorical comparison. The data originates from a CSV file, and the code uses `d3.scaleBand` for the y-axis and `d3.scaleLinear` for the x-axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bfa8b4168ebf416ab1e391cb16f07d56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
