{"version":"1.0","type":"rich","title":"Activity6_bubblechart-TASK4","description":"This interactive bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across 31 car makes. Each bubble represents a make, positioned by its horsepower on the x-axis and torque on the y-axis, while bubble radius encodes highway MPG and color distinguishes makes. The visualization uses D3 v7 to load data from a CSV file, render SVG elements with linear scales for all three variables, and includes interactive tooltips that display the make name on hover. A legend explains the bubble size scaling and color mapping for each make.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4728c129894404dad72f86f9a581070?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
