This interactive scatter plot lets users explore the relationship between any two numeric columns from the auto-mpg dataset by selecting axes from dropdown menus. The visualization demonstrates a unidirectional data flow pattern, where menu selections trigger re-renders of the entire chart. Built with D3 v5, it uses scaleLinear, axisBottom, axisLeft, and transition methods to animate circles from the center to their positions. The General Update Pattern is applied through enter/merge selections, and the subtle animations use staggered delays for a cascading effect.
