This interactive scatter plot visualizes the Iris dataset, allowing users to explore relationships between sepal and petal dimensions by selecting different attributes for the x- and y-axes via dropdown menus. The visualization uses d3.scaleLinear for axis scaling, d3.select for DOM manipulation, and d3.axisBottom and d3.axisLeft for rendering axes with gridlines. Data points are rendered as SVG circles, colored by species class (setosa, versicolor, virginica) with opacity for overlap handling. The React framework manages the dropdown state, while D3 handles the chart rendering.
