{"version":"1.0","type":"rich","title":"Activity_6_Tutorial 4","description":"This visualization 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, scaled linearly via d3.scaleLinear. Color is mapped to car make using a d3.scaleOrdinal with interpolated turbo colors. The SVG includes axes with labels, a size legend for MPG, and a color legend for makes. Interactive tooltips appear on mouseover, showing the make, using d3 event handlers. Data is loaded from a CSV file and animated with D3 v7 transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22354f5f5df0469d9d51726fb67a8163?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
