This interactive scatter plot visualizes the Iris dataset, displaying measurements of sepal and petal length and width as colored circles representing Iris setosa, versicolor, and virginica species. Users can dynamically change the x- and y-axis features via dropdown menus, causing the visualization to re-render. Built with D3 v7, the chart uses `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and SVG circles with opacity to plot data points. The color legend matches each species, and axes are labeled based on the selected feature.
