{"version":"1.0","type":"rich","title":"Activity 6_Task 4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its radius and color represent highway MPG and car make, respectively. Built with D3.js v7, the visualization renders as SVG with interactive tooltips on mouseover, a size legend for MPG values, and a color legend for makes. Data is loaded from a CSV file using `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/77f7c7fb89a94762b66da66db5f1d800?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
