{"version":"1.0","type":"rich","title":"tutorial 4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across various car makes. Each bubble’s position encodes horsepower on the x-axis and torque on the y-axis, while its size represents highway MPG, and color distinguishes car manufacturers. The chart, built with d3.v7’s SVG API, includes tooltips on mouseover, a legend for bubble size, and a color scale using d3.interpolateTurbo and d3.scaleOrdinal. Data is loaded from a CSV file, with animated hover effects to highlight individual bubbles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1dd80e2cb724cc5bf6eea0c6a825046?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
