{"version":"1.0","type":"rich","title":"Bubble chart","description":"A bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with bubble size encoding MPG and color distinguishing manufacturers. D3.js v7 loads the CSV data and renders the SVG chart with linear scales for axes and bubble radius, plus an ordinal color scale using `d3.interpolateTurbo`. Hovering reveals a tooltip showing the car make, while custom legends display both the MPG size mapping and color-coded manufacturer categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/478f4b3b9c064b2799529194f02bf9c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
