This scatter plot visualizes the Iris dataset, mapping petal length and width to the x and y axes, with each species (Setosa, Versicolor, Virginica) represented by a distinct color (black, magenta, beige). The chart also encodes sepal length and width as the horizontal and vertical radii of elliptical markers, creating a multivariate display. Built with React, it loads CSV data via `d3.csv` and uses D3.js v6 functions including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to render the SVG and axes.
