The x-axis maps the year, the y-axis lists drivers sorted by their first winning year, circle size encodes starting position, and color distinguishes tracks. Built with Vega-Lite API, it loads CSV data via D3’s `csv` function and renders to SVG using Vega’s renderer, with tooltips enabled through Vega Tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9839bc92a7e84be8a885b4b1a02c242e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
