{"version":"1.0","type":"rich","title":"activity6_tutorial4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across various car makes from a CSV dataset. Each circle represents a car brand, with its position determined by the x- and y-scales for horsepower and torque, while the circle’s radius encodes highway MPG using a linear scale. The chart uses d3.csv to load the data, d3.scaleOrdinal with interpolateTurbo for color mapping by make, and SVG circles with mouseover, mousemove, and mouseleave handlers to display a tooltip. A legend shows MPG values and make colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ff3723bd885421f89fc865fe2538002?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
