{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 30 car makes. Each circle’s position maps horsepower and torque, while its radius encodes highway MPG and its color distinguishes the make. The visualization uses d3.csv to load data, d3.scaleLinear for axes and sizing, and d3.scaleOrdinal with interpolateTurbo for categorical coloring. Interactive tooltips appear on mouseover, and a legend explains size and color encoding. The chart is rendered as SVG with animated hover effects, styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ddd673abb0f44f72924b7272b7d776d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
