This example visualizes the Iris Dataset as a scatter plot, mapping petal length and width to the x and y axes, while encoding the species of each flower with color (blue, red, or black). It also encodes the sepal measurements into the shape of each point through the `rx` and `ry` attributes, adding an extra dimension of data. Built with D3 v6 and rendered as an SVG, the code loads the data using `d3.csv`, deploys `select`, `scaleLinear`, `extent`, and the `axisLeft` and `axisBottom` helpers to produce the chart.
