{"version":"1.0","type":"rich","title":"Activity_Task 4","description":"This interactive bubble chart visualizes correlations between average horsepower, torque, and highway MPG across 31 car makes from a CSV dataset. Each bubble’s x-position maps to horsepower, y-position to torque, and radius to highway MPG, with color encoding make identity. Built with d3.v7, the SVG chart features a linear radius scale, ordinal Turbo color scale, and hover tooltips displaying the car make. The visualization includes two legends: one for bubble size representing MPG values and another color-coded legend listing all makes. Interactive mouseover events trigger tooltip transitions showing contextual data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac28942f3a4d4728a58febfca9878f98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
