{"version":"1.0","type":"rich","title":"act6 question4","description":"This bubble chart explores the correlation between a vehicle's torque, horsepower, and highway MPG. The chart uses `d3.scaleLinear` for the x and y axes and for bubble radius, with a `d3.scaleOrdinal` for color-coding by car make. Interactive tooltips appear on mouseover, implemented with D3's selection and event handling. A legend for the bubble size scale is also included. The visualization is rendered as an SVG and uses D3's `d3.csv` to load data from a local file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/90079e0bd31241a099bf7ac8b8ab0aa3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
