{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with bubble size encoding MPG and color distinguishing brands. Built with React and D3 v7, the SVG chart uses d3.scaleLinear for axes and bubble radius, d3.scaleOrdinal for color, and d3.axisBottom/axisLeft for ticks. Interactive tooltips appear on mouseover, while legend circles and labels show MPG values. Data comes from the bundled bubblechart.csv file, rendered with animated transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/218f81dd2a514e7587a474766f4ef0df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
