This interactive scatter plot visualizes the Iris dataset, showing relationships between sepal and petal measurements, with points colored by species (setosa, versicolor, virginica). Users can select which measurement to display on the x- and y-axes via dropdown menus. Built with D3 v5, the visualization uses `d3.csv` to load the data, `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.scaleOrdinal` for color encoding, rendering points as SVG circles.
