{"version":"1.0","type":"rich","title":"Scatterplot","description":"This scatterplot visualizes the relationship between fuel efficiency and engine size for a dataset of cars, with each point’s radius representing horsepower and its opacity representing price. The chart uses D3 v6 to load CSV data from a GitHub gist, apply linear scales for the axes and point attributes, and render circles in an SVG. Color encodes car type (Sedan, Coupe, SUV, Truck) via `d3.scaleOrdinal`, with a legend included. Axes are drawn using `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99ed3365166a4ff68c5703b9d8e36623?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
