{"version":"1.0","type":"rich","title":"Activity 6_Question 4","description":"This interactive bubble chart visualizes the correlation between average engine power, torque, and highway fuel efficiency across various automobile makes. Each circle’s x-position maps to engine power, its y-position to torque, and its radius to fuel efficiency, with color distinguishing makers. Built with D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.interpolateTurbo` for encodings, plus mouse event handlers for tooltips. The SVG render includes axis labels and a legend for bubble size, sourced from automakers.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95fb114ce1074d2a82b33fc34f50df36?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
