{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A bubble chart shows how average horsepower, torque, and highway MPG correlate for 31 car brands, with each circle’s x-position mapping to horsepower, y-position to torque, and radius to highway MPG. Color encodes the car make, and a tooltip displays the brand on hover. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for colors, and SVG circles with mouse-event handlers for interaction. Data is loaded via `d3.csv` from a local file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3eb1aa2aa36741efa500f8630c3e5649?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
