{"version":"1.0","type":"rich","title":"Activity7_task5","description":"This interactive bubble chart displays the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower and torque, while its radius represents highway MPG, and color distinguishes the make. The visualization includes a tooltip showing the make on hover, plus legends for bubble size and color categories. Built with D3 v7, it loads data from a CSV file, uses SVG rendering, and implements hover interactions through mouse events and D3 transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/50ff887a837a48cb9515b46d677157de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
