{"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. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius represents highway MPG and its color distinguishes the car brand. Hovering over a bubble reveals the make via a tooltip built with D3’s event handlers. The visualization uses d3.scaleLinear axes, d3.scaleOrdinal for color, d3.interpolateTurbo for the palette, and SVG circles animated through d3 transitions. Data comes from bubblechart.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a91e0dd37a5d4276917e0154adf48054?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
