{"version":"1.0","type":"rich","title":"Tutorial 4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with each bubble positioned by horsepower (x-axis) and torque (y-axis), while its radius and color encode highway MPG and make, respectively. Built with D3.js v7, the SVG chart includes animated mouseover tooltips that display the car make, and a legend showing MPG scale and color-coded makes. It reads from a CSV file, uses linear scales for axes and bubble size, and applies an ordinal color scale using interpolateTurbo.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f02a440e0a14a6f8a54d8d9a722681a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
