{"version":"1.0","type":"rich","title":"tutorial4","description":"This animated bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. 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 car make, respectively. Built with D3 v7, the SVG renders tooltips on mouseover, a size legend for MPG values, and a categorical color legend. Data is loaded from a CSV file, with linear scales and `d3.scaleOrdinal` driving the encoding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9900b3f98a54603bdf457261c7db3b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
