This interactive scatter plot visualizes the Iris dataset, with dropdown menus controlling the attributes mapped to the x and y axes. The visualization is rendered using React and D3 v5, leveraging `d3.scaleLinear`, `d3.extent`, and `d3.format` to compute scales and tick formatting. Each data point is drawn as a circle with a tooltip showing its x-value. Selecting different attribute combinations updates the axes and marks dynamically, allowing exploration of relationships among sepal and petal measurements.
