This scatter plot shows the Iris dataset across four selectable dimensions. Users choose which measurement (sepal length, sepal width, petal length, or petal width) to plot on each axis, and the plot redraws accordingly. The visualization uses D3 scales (`scaleLinear`, `scaleOrdinal`) to map data to positions and colors, with each flower class assigned a distinct color. The SVG rendering includes axes, gridlines, a title, and a legend, and it updates in response to the interactive dropdown selectors.
