This interactive scatter plot uses the D3 library to visualize relationships between pairs of attributes from the auto-mpg dataset. Two dropdown menus let the user select which columns to plot on the x and y axes. The visualization employs `scaleLinear` to map data to screen coordinates and `axisLeft` and `axisBottom` to render axes. Points animate into place using D3 transitions, with each circle's `cx` and `cy` attributes tweened over 500 milliseconds when the axis selection changes.
