{"version":"1.0","type":"rich","title":"NASCAR Dashboard IV- Dropdowns, Different Plots","description":"This dashboard displays four NASCAR visualizations: a map of track locations, bar charts of driver starts before first wins and top winners, and a scatter plot of starting positions among winners. Each visualization includes an independent dropdown menu and interactive tooltips, with points and bars resizing based on selections. Built with d3.v5 and the Vega-Lite API, the visualizations use `vl.selectSingle` with a menu binding for filtering, `markGeoshape` and `markCircle` for the map, and `markBar` for histograms. The data is loaded via D3’s `csv` from GitHub gists, with tooltips handled by Vega Tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5ebc58a9dc5c4ca29257f9ee64682dea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
