{"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, with circle size encoding MPG and color representing manufacturer. The D3.js v7 code uses `d3.csv` to load data, `d3.scaleLinear` for x, y, and radius scales, and `d3.scaleOrdinal` with `d3.interpolateTurbo` for color. SVG circles render with interactive tooltips on mouseover, alongside a legend showing MPG values and color-coded makes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8aec9950a7104ae3bc175b760136a5ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
