{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each vehicle brand represented by a colored circle positioned by horsepower and torque while its size encodes fuel efficiency. The visualization uses D3.js v7 with SVG rendering, employing `d3.scaleOrdinal` with `d3.interpolateTurbo` for color assignment, `d3.scaleLinear` for positional and size scales, and interactive tooltips triggered by mouse events. Data comes from a CSV file containing per-make averages, and the chart includes dual legends for bubble size and make-color mapping. Animation is not present despite the metadata listing.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4cb6b54bddeb46bcaf559d6e2d7e0930?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
