This example displays the Iris dataset through a scatter plot, mapping petal length and width to the x- and y-axes while coloring points by species (setosa, versicolor, or virginica). The visualization uses D3 v6 to load CSV data, apply linear scales with `d3.scaleLinear`, and render circles in an SVG container. It also draws axes via `d3.axisBottom` and `d3.axisLeft`, with labeled axis text, and handles the full window size for the plot area.
