This interactive scatter plot lets users explore the relationships between different attributes of cars from the auto-mpg dataset. Two dropdown menus allow selection of the x and y variables, dynamically re-rendering the axes and data points. The visualization uses d3.v5 with SVG and animation, employing `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` for scales and axes. Circles transition smoothly to new positions when the selected columns change, and a tooltip appears on hover to show each car's details.
