{"version":"1.0","type":"rich","title":"NASCAR Winners by Starting Position, Dropdown Added","description":"This scatterplot shows NASCAR winners’ starting positions across race years from 1975 to 2003, with each point colored by track name and sized by track length. A dropdown menu filters the view to a single track, dimming non-selected points. The visualization is built with Vega-Lite and D3 v5, using `vl.selectSingle` and `vl.menu` for the interactive filter, and it loads data from a CSV via `d3.csv` to encode categorical colors and quantitative positions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/67536079259a4a84862e05fe546cff2d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
