{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive D3.js v7 bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes from a CSV file. Each circle’s position maps horsepower and torque values, while its radius encodes MPG and its color distinguishes the manufacturer. The visualization includes a tooltip that displays the make on mouseover, plus dual legends for MPG scaling and color-coded makes. The SVG rendering uses d3.scaleLinear for axes and bubble size, d3.scaleOrdinal for categorical coloring, and d3.interpolateTurbo for the color palette.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e4d5cd1cf6ed4b4d82d8df27034354b6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
