This interactive visualization displays the classic Iris dataset, showing measurements of sepal and petal dimensions for three flower species. Dropdown menus allow users to select which attributes map to the X and Y axes, updating the scatter plot through D3 v5 data joins. The SVG rendering uses d3.scaleLinear for axes, d3.axisLeft, and d3.axisBottom with gridlines, while colored circles animate to new positions via transition().duration(). The plot includes a legend identifying the three Iris classes and uses a custom color function.
