{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its radius represents highway MPG. Bubbles are colored by car make, using a turbo colormap through `d3.interpolateTurbo` and `d3.scaleOrdinal`. An interactive tooltip displays the make on hover, implemented with `.on('mouseover')` callbacks. The chart also includes a size legend for MPG values derived from the `z` scale, with data drawn from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6994d8d3fdb2432d93214fbc7c27883d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
