This visualization displays the Iris dataset as a scatter plot of petal length against petal width, with each species represented by a distinct shape and color: setosa as skyblue circles, versicolor as lightgreen squares, and virginica as orange triangles. A red title labels the chart, and the axes are green with larger fonts. The code uses D3 v6 to load CSV data via `d3.csv`, scales with `scaleLinear`, and draws marks using `d3.symbol` with `symbolCircle`, `symbolSquare`, and `symbolTriangle`. Axis rendering employs `axisLeft` and `axisBottom`.
