{"version":"1.0","type":"rich","title":"Fork of NASCAR history of drivers and tracks","description":"This example visualizes NASCAR race winners by starting position, using a circle plot where each dot’s size encodes the starting position and its color represents the track. Drivers are sorted by year on the y-axis, with the year on the x-axis. The visualization is built with Vega-Lite, using the `vl.markCircle` API for encoding, and loads CSV data via `d3.csv` from a remote GitHub gist. The chart uses `vl.x().fieldN('Year')` and `vl.y().fieldN('Driver')` for axes, with tooltips for driver and track details.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00b41c062b26471c9450a3581aec775c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
