{"version":"1.0","type":"rich","title":"Question3","description":"This example shows a scatter plot of car weight versus fuel efficiency (MPG), using a small CSV dataset with ten vehicles. Each point is colored by manufacturer, with a legend listing the distinct brands. The visualization is rendered as an SVG using D3 v6, employing `d3.csv`, `scaleLinear`, `axisLeft`, `axisBottom`, and `scaleOrdinal`. Axes are labeled for weight and MPG, with margins and a title, demonstrating basic data loading, scaling, and legend construction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9b757b8f86f9496693525fe44b411d3e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
