{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s x and y position corresponds to horsepower and torque, while its radius encodes highway MPG, and color distinguishes the make. Hovering reveals the make label via a D3 tooltip. Built with d3.v7, it uses SVG rendering with scales for position, size, and ordinal color, and includes legends for size and color mapping. Data comes from the included `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c4eee7f9ec4b4824ad602776a12ce2d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
