{"version":"1.0","type":"rich","title":"Activity6-Task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across various car makes. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius and color represent highway MPG and car make, respectively. Built with D3 v7, the SVG animation includes interactive tooltips on hover, a custom legend for MPG bubble sizes, and a color-coded legend for makes. Data is loaded from a CSV file, with scales defined via d3.scaleLinear and colors assigned using d3.scaleOrdinal with d3.interpolateTurbo.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7f82141f0ab48bc9d5db155b8239f30?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
