This interactive scatter plot displays the Iris dataset, encoding measurements like petal length and width as circle positions. Dropdown menus let users switch which attributes map to the x and y axes. The visualization renders using SVG within a React component, leveraging D3's `scaleLinear`, `extent`, and `nice` for axis scaling and ticks. Custom `AxisBottom` and `AxisLeft` components handle tick marks, while `Marks` draws labeled data points.
