This scatter plot visualizes the Iris dataset, mapping petal length on the x-axis and sepal width on the y-axis. The React-based application loads the data using the `d3.csv` utility, then renders SVG circles positioned through `d3.scaleLinear` scales. Hovering highlights each point by changing its fill color to orange. Axes are generated with `d3.ticks` through the custom `AxisBottom` and `AxisLeft` components, while titles provide tooltips when points are selected.
