{"version":"1.0","type":"rich","title":"Bubble chart","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for 31 car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its radius and color represent highway MPG and car brand, respectively. Built with D3 v7, the SVG graphic uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for categorical colors, and an animated tooltip that appears on mouseover. Data is loaded from a local CSV, and the legend clarifies size and color mappings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5ff84a583e84c739e818d91bcd32e85?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
