{"version":"1.0","type":"rich","title":"task 4 tutorial","description":"This example visualizes the correlation between average horsepower, torque, and highway MPG for various car makes using a bubble chart. Each bubble’s position reflects horsepower and torque, its size encodes highway MPG, and its color distinguishes car makes via a `d3.scaleOrdinal` with `d3.interpolateTurbo`. The chart includes axes, a size legend, and an interactive tooltip that appears on hover using mouse events. Data is loaded from a local CSV file with `d3.csv`, and rendering is done through SVG elements with D3 v7.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/90510cdf72bc4c29af5e281a6171a393?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
