{"version":"1.0","type":"rich","title":"Activity6_Q9","description":"This bubble chart compares engine performance across car makes, plotting horsepower on the x-axis against torque on the y-axis while encoding highway fuel efficiency as the radius of each circle. The color of each bubble corresponds to the car manufacturer, using a categorical scale with `d3.schemeTableau10`. The visualization is rendered as SVG using D3 v7, with linear scales for the axes and a sqrt scale for bubble size. Data comes from a local `cars.csv` file with aggregated values per make.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9e2e08c8690e4376884dc1719902f970?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
