{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across various car makes, using data from `bubblechart.csv`. The chart encodes horsepower on the x-axis, torque on the y-axis, and highway MPG as both bubble size and color, with a legend and interactive tooltips. Built with React and D3 v7, it uses `d3.scaleLinear` for axes and bubble scaling, `d3.scaleOrdinal` for color assignment, and SVG animation for hover effects. The visualization is rendered via `d3.select` and `.join` operations, with tooltips appearing on mouseover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/833e38a48ef641d6ab4a8d8d11aa7723?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
