{"version":"1.0","type":"rich","title":"Exercise8_Tutorial4","description":"This bubble chart visualizes the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size and color) across 31 car makes. Using d3.csv to load data, the chart renders SVG circles scaled by a linear d3.scaleLinear for size, with an ordinal color scale applying d3.interpolateTurbo. Interactive tooltips appear on mouseover, while a legend shows MPG value ranges and make colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b7fe1b3214f74dd4a17a0e03afc864d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
