This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal measurements across species. Dropdown menus dynamically change the X and Y axes, redrawing the SVG circles and axis labels in real time. Built with React and D3 v5, the visualization uses `scaleLinear` for axis scaling, `extent` for domain calculation, and custom `AxisBottom`, `AxisLeft`, and `Marks` components for rendering. Data is loaded asynchronously via `csv()` from a remote URL, with tooltips showing formatted values. The chart includes styled tick marks, axis labels, and a clean Poppins font.
