This visualization shows NASCAR race winners across years, with each circle representing a driver’s starting position in a race. 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.
