{"version":"1.0","type":"rich","title":"Plot of NASCAR Winners by Payout","description":"This scatterplot displays NASCAR race winners from 1975 to 2003, plotting the year of the race against the payout amount. Points are colored by track name and sized by track length, revealing patterns such as larger superspeedways producing winners from further back in the field. The visualization uses d3.v5 for data loading via `d3.csv` and the Vega-Lite API to encode the marks, with a custom tooltip showing driver and track information. The data comes from a GitHub-hosted winners.csv dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/057ea24503334f7fb69b096191436c10?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
