{"version":"1.0","type":"rich","title":"Question-4","description":"This bubble chart visualizes the correlation between power output, torque, and efficiency rating for various car manufacturers. Each bubble's position maps to power and torque on the x and y axes, its size encodes efficiency rating, and its color distinguishes the manufacturer. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for color encoding, and SVG circles for rendering. Interactive tooltips appear on mouseover, displaying manufacturer details, while a legend indicates efficiency values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86ebc9a9a17248b1a719cea837fc1367?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
