This interactive scatter plot displays the classic Iris dataset, allowing users to compare any two of the four measured features (sepal and petal length/width) by selecting them from dropdown menus. The visualization uses D3 v7 to render an SVG, with `scaleLinear`, `axisLeft`, and `axisBottom` constructing the axes, while `csv` loads the local iris data. Points are colored distinctly for the three Iris species, with a legend and gridlines, and the chart redraws dynamically on selection changes.
