{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive bubble chart shows the correlation between average horsepower, torque, and highway MPG across different car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its radius represents highway MPG, and its color represents the car brand. Hovering a bubble displays a tooltip with the make name. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble sizing, `d3.interpolateTurbo` for the color scale, and SVG circles with mouse event handlers for interactivity. Legend circles and labels clarify the MPG scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e92867b8b40f4e00b6497aac3726de22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
