{"version":"1.0","type":"rich","title":"Tutorial Task 4","description":"This visualization displays the correlation between average horsepower, torque, and highway MPG across various car makes. Each bubble’s position maps horsepower on the x-axis and torque on the y-axis, while its size and color encode fuel efficiency via a linear scale and a sequential viridis color scale. The code uses d3.csv to load data, d3.scaleLinear for axes and radii, and d3.scaleSequential for coloring. Interactive tooltips appear on mouseover, and a gradient legend clarifies the MPG color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fc2d4b1905f947b7a1459b494144295c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
