This scatter plot visualizes the Iris dataset by mapping petal length and petal width for each sample, with points colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica). The visualization uses D3 v6 APIs including `d3.csv`, `scaleLinear`, `axisLeft`, and `axisBottom` to render SVG circles and axes. Additional sepal length and width values are encoded but not directly displayed. The data is loaded from a GitHub gist and rendered across the full browser window with rotated axis labels for petal length.
