This scatter plot visualizes car attributes from the UCI Auto MPG dataset, displaying relationships between selectable variables like horsepower, weight, and acceleration. Users choose axes through dropdown menus, while a color legend highlights car origins (US, Europe, Japan) and toggles highlighting of specific regions. The visualization uses D3 v5 with SVG rendering, employing `scaleLinear`, `axisLeft`, `axisBottom`, and `scaleOrdinal` for axes and color mapping. Hovering reveals car names via `title` elements, and clicking legend items filters data opacity.
