This interactive scatter plot visualizes the Iris dataset, displaying sepal and petal measurements for individual flowers. Users can select which attributes to plot on the X and Y axes using drop-down menus, with both axes updating dynamically to reflect the chosen variables. The visualization is built with React and rendered as SVG, using D3's `scaleLinear` and `extent` functions to compute scales and domains. Axis components are custom React components that generate tick marks and labels, while the `Marks` component renders circles with tooltips for each data point.
