{"version":"1.0","type":"rich","title":"Activity6_Tutorial4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle represents a car brand, positioned by horsepower and torque, with its size encoding highway MPG and color distinguishing makes. The visualization uses D3.js v7’s `scaleLinear` for axes and bubble scaling, `scaleOrdinal` with `interpolateTurbo` for colors, and SVG rendering with interactive tooltips on hover. A legend shows bubble size values, while color coding identifies each make.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2aa579af82ea42ec8740db24c2aad30d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
