This visualization displays the classic Iris dataset as a scatter plot, mapping petal length and sepal length along the x and y axes while encoding species type through point color (sky blue for setosa, light green for versicolor, and orange for virginica). Built with D3 v6, the example uses `csv` to load the data, `scaleLinear` and `extent` for axes, `axisLeft` and `axisBottom` for tick marks, and SVG circles to render the points. Circles also encode sepal length and width as additional attributes, though these do not alter visual appearance.
