{"version":"1.0","type":"rich","title":"Activity6 task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble's position corresponds to its horsepower (x-axis) and torque (y-axis), while its size scales with highway MPG. Bubbles are color-coded by make, and the chart includes a legend for MPG values and car makes. Built with D3 v7, it renders as SVG, uses `d3.scaleLinear` for axes and sizing, and features interactive tooltips displaying the make on mouseover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/816cf865d2534239bd8dd7dd30768852?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
