{"version":"1.0","type":"rich","title":"Stacked bar","description":"This stacked bar chart shows the top 10 NASCAR drivers by total wins across different tracks from 1975 to 2003, with each bar segmented by track and colored accordingly. It uses vega-lite API to create the visualization, loading data from a CSV file via d3.csv. The bars are sorted descending by win count, and a tooltip displays the driver name and track-specific win totals. The color scale maps track names to distinct colors, while config.js customizes axis and label styling. The encode method specifies x, y, and color channels with count aggregation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/89481e9aa568414fb6aa2b48ce7413e8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
