This interactive scatter plot visualizes the Iris dataset, allowing users to compare any two of the four flower measurements (sepal length/width, petal length/width) via dropdown menus. The visualization uses D3 v6 within a React framework, rendering SVG circles colored by species (setosa, versicolor, virginica). The code leverages d3.scaleLinear, d3.extent, d3.axisBottom, and d3.axisLeft to construct axes, while the dropdown menus update the chart dynamically by re-scaling and re-plotting the data points. Data is loaded from a CSV file.
