{"version":"1.0","type":"rich","title":"Tutorial4","description":"This bubble chart explores the relationship between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its radius represents highway MPG and its color distinguishes the car manufacturer. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and SVG circles with interactive tooltips on mouseover. The legend explains both the MPG sizing and the color mapping for each make based on data from `bubblechart.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4819f0b036794c909f9bb1cb303ce104?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
