{"version":"1.0","type":"rich","title":"A6_t4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes using D3.js v7. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius and color represent highway MPG and the car make, respectively. An interactive tooltip appears on mouseover using the `.on` event handlers, and a legend decodes the MPG bubble sizes. The chart reads data from `bubblechart.csv` and renders via SVG with smoothed color transitions from `d3.interpolateTurbo`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/818bd8189a804fceaf586095126b9c8d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
