This example visualizes the Auto MPG dataset from the UCI Machine Learning Repository, plotting array values against props4 as bar marks with a tooltip showing props2. Built with the Vega-Lite API, it registers Vega and Vega-Lite libraries, configures axis styling with dark labels and yellow ticks, and uses D3’s csv loader to fetch remote data. The visualization renders full-window with SVG output, enabling interactive tooltips via Vega-Tooltip.
