{"version":"1.0","type":"rich","title":"Nascar Dashboard I- Just Plots","description":"This dashboard presents four NASCAR data plots: a map of track locations, a bar chart of starts before first wins, a stacked bar chart of top drivers by track, and car maker finishes. It uses the Vega-Lite API with `vl.markCircle`, `vl.markBar`, and `vl.layer` to render the visualizations. The map uses an Albers USA projection from a topojson file, while other plots pull data from remote CSVs. Interactive multi-selection via `vl.selectMulti` filters points and bars by track name, adjusting opacity for highlighted marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/003350ee01e643e382c6d73944447271?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
