This interactive scatter plot lets viewers explore the relationship between different attributes of cars from the classic Auto MPG dataset by selecting which columns map to the X and Y axes via dropdown menus. The visualization uses D3.js (version 5) to render circles with animated transitions, scaling each axis with `d3.scaleLinear` and adding axes via `d3.axisBottom` and `d3.axisLeft`. The user can compare variables such as miles per gallon, horsepower, and weight.
