This example shows a scatter plot of iris flower measurements, with sepal length on the x-axis, petal length on the y-axis, and species encoded by ten distinct symbol shapes from d3.symbolsFill. A shape legend identifies each species marker. Using D3 v7, the code loads data from a remote CSV via fetch and csvParse, then renders the plot with d3.scaleLinear for axes, d3.axisBottom/axisLeft for ticks, and d3.symbol to generate the shape paths.
