{"version":"1.0","type":"rich","title":"Activity6_task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its size and color represent highway MPG and the car make, respectively. Built with D3 v7, the SVG chart includes hover tooltips, a legend for bubble size, and color-coded categories. Data is loaded from a CSV file via `d3.csv`, with linear scales for axes and bubble sizing, and an ordinal color scale using `d3.interpolateTurbo`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5f979a2cedd4f588a3bee9f7db1c12d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
