{"version":"1.0","type":"rich","title":"NASCAR Dashboard III- Dropdowns Added","description":"This dashboard displays four NASCAR statistics visualizations: a U.S. track map, a bar chart of starts before first wins, a scatterplot of starting positions among winners, and a car maker finishes chart. Each view includes its own dropdown menu that filters by track name, implemented with `selectSingle` and `bind.menu` from vega-lite-api. Points and bars reset with a click, and hovering reveals tooltips via vega-tooltip. Data is loaded asynchronously with d3.csv from GitHub gists.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f6870526ff1c4d1ba3028c017544b995?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
