{"version":"1.0","type":"rich","title":"[A6] Vehicle Power vs. MPG (Scatter Plot With Qualitative Color Scale)","description":"This scatter plot compares vehicle torque and horsepower, with each point’s size encoding MPG. The chart uses a qualitative color scale to distinguish car makes—Audi in blue, Chevrolet in red, and Volvo in green—via `d3.scaleOrdinal` and a `d3.legendColor` legend. Data from a CSV file is loaded with `d3.csv`, parsed, and mapped to linear scales for the x- and y-axes, while circle radii are scaled by MPG using `d3.scaleLinear`. The SVG rendering is handled by D3 v7, with axes, labels, and a triangular-symbol legend drawn programmatically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cf6921ca3f4846d78331f3a702256c62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
