This interactive scatter plot displays relationships between pairs of numerical attributes of cars, using data from the UCI Auto MPG dataset. It shows one attribute on each axis, with red, semi-transparent circles representing individual cars, enabling pattern exploration across different variables. The visualization employs HTML `<select>` menus, built with custom JavaScript, to dynamically switch the x and y axes. Rendering uses D3 version 5's `select`, `scaleLinear`, `axisBottom`, `axisLeft`, and `csv` modules, with a `transition` animation for a 1000-millisecond circle movement when axes change.
