{"version":"1.0","type":"rich","title":"Activity_Question-2","description":"This example displays a stacked bar chart comparing three vehicle performance metrics—horsepower, torque, and highway MPG—across 31 car makes. The bars are sorted by increasing horsepower, revealing a trade-off between raw power and fuel efficiency. Built with D3 v7, the visualization uses a linear scale for the y-axis and a band scale for categorical x-axis values. Data comes from a CSV file containing average specifications per make, rendered as SVG `rect` elements with the `.bar` class.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6072cbcc673e46d585e95834d4e7df22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
