This example shows a scatter plot of the Iris dataset, mapping sepal length to the x-axis and petal length to the y-axis, with each species represented by a distinct symbol shape. A legend on the right identifies the three species categories, while axis labels clarify the measurement values. The visualization loads data from a remote CSV file using `csvParse` and renders marks with `d3.symbol` and `symbolsFill`. Axes are drawn using `axisLeft` and `axisBottom`, with scales from `scaleLinear` and `scaleOrdinal` assigning positions and shapes.
