This visualization displays relationships among automobile characteristics from the UCI Auto MPG dataset, encoding miles per gallon and horsepower on the axes, origin as color, and weight as point size. Built with Vega-Lite's API wrapper, the code uses `vega-lite-api` to construct a circular mark encoding specification, then renders interactively through Vega and Vega-Lite. The visualization includes tooltips for car names, styled with custom axis and label configuration for improved readability.
