An interactive scatter plot of the Iris dataset displays measurements of sepal and petal dimensions, with each of the three species rendered in a distinct color and identified in a fixed legend. Users select attributes for the x- and y-axes from two dropdown menus. The chart uses D3 v5 scales and axes (`scaleLinear`, `axisLeft`, `axisBottom`), with circles animated via `transition().delay()` as they reposition. Data is loaded asynchronously from a CSV file, and SVG rendering is updated dynamically upon menu selection.
