{"version":"1.0","type":"rich","title":"Activity6_tutorial4","description":"This bubble chart shows the relationship between average horsepower, torque, and highway MPG for different car makes, using D3.js. The x-axis represents horsepower, the y-axis represents torque, and the size of each bubble corresponds to highway MPG. The data is loaded from a local CSV file via `d3.csv()` and rendered as SVG circles with tooltips. Color is mapped by car make using `d3.scaleOrdinal` with an `interpolateTurbo` palette, and a legend displays the MPG size scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de2812466ad04b8eaca925ec11b33505?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
