This interactive scatter plot visualizes the Iris dataset, displaying measurements such as petal and sepal length and width. Users can dynamically select which measurements appear on the x- and y-axes via dropdown menus, with all points rendered as SVG circles. The visualization is built using React and D3 v5, leveraging D3’s `scaleLinear` for axis scaling and `csv` for data loading. Axis ticks and labels are generated with custom React components, while a tooltip shows formatted values on hover.
