{"version":"1.0","type":"rich","title":"Question-4","description":"A bubble chart shows the correlation between average horsepower, torque, and highway MPG for different car makes. Each circle's x-axis position maps to horsepower, y-axis to torque, and radius encodes highway MPG. The color represents the car manufacturer, with a legend for MPG values and the make categories. Implemented with D3 v7, it uses `scaleLinear` for axes, `scaleOrdinal` for coloring, and interactive tooltips that appear on mouseover, including transitions on hover. Data comes from a CSV file loaded via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/919019df1641460c956cd27eef08a797?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
