{"version":"1.0","type":"rich","title":"activity-6_4","description":"This bubble chart displays the relationship between average horsepower and average torque for various car makes, with a third dimension (highway MPG) represented by bubble size and car make encoded by color. Built with D3 v7, the visualization uses `d3.scaleLinear` for both axes, `d3.scaleSqrt` for bubble sizing, and `d3.scaleOrdinal` with the Tableau10 scheme for categorical coloring. Interactive tooltips appear on hover, showing the exact values for each car make. The chart reads from a local CSV file and renders as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd5d0e76f3b14c62804b58da79184b70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
