{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its radius and color represent highway MPG and car make, respectively. Built with D3 v7, the SVG visualization includes a tooltip on hover, a size legend for MPG values, and color-coded makes. Data is loaded from a local CSV file, with scales and axes created via `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58ee10b08a5e471496c091550f5f6336?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
