{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s x-position maps to horsepower, y-position to torque, and radius to fuel efficiency, while color distinguishes the manufacturer. The D3.js code uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for categorical colors, and interactive tooltips via mouseover events. A legend encodes MPG values and car makes, with all elements rendered as SVG shapes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bdaaf29e241d413ea7cd7a045a82e246?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
