{"version":"1.0","type":"rich","title":"Activity-6_Task-4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes, with bubble size representing fuel efficiency and color encoding car brand. The D3 v7 visualization reads data from a CSV file and uses d3.scaleLinear for axes and bubble sizing, d3.scaleOrdinal for color mapping, and d3.interpolateTurbo for the color palette. Interactive tooltips appear on mouseover using d3 event handlers, while a legend displays both bubble size values and color-coded makes. The SVG rendering includes axis labels, a title, and animated hover effects.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ae7e3d501d1243a9b309249a87fdd8bf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
