This visualization displays the relationship between the origin of a car and its horsepower using data from the UCI Machine Learning Repository’s Auto MPG dataset. Rendered as a circular scatter plot, each point represents a car, with opacity enhancing readability when points overlap. The code leverages the Vega-Lite API, specifically `vl.markCircle` and `vl.encode` for visual encoding, while `d3.csv` handles data loading. The visualization automatically fits the browser window and includes a custom tooltip via Vega-Tooltip, with axis styling customized through a separate configuration file.
