This interactive scatter plot lets users explore the auto-mpg dataset by selecting which columns to map to the x-axis, y-axis, and color encoding through three dropdown menus built with a reusable D3 component. The scatter plot is rendered as SVG using D3 scales, axes, and animated transitions that grow circles from the center. A color legend, generated via a custom component, displays the categorical color scale. The visualization demonstrates dynamic data binding and reusable chart modules in D3 v5.
