This visualization is a scatter plot of the Iris dataset, showing sepal length on the x-axis against petal length on the y-axis, with each point’s shape encoding the species of iris. A shape legend identifies the species categories. Built with D3 v7, the code uses `scaleLinear` for the axes, `scaleOrdinal` with `symbolsFill` to map species to distinct shapes, and `symbolGenerator.type().size()` to render each point’s path. The data is loaded remotely as a CSV and parsed with `csvParse`.
