This visualization displays the classic Iris dataset as a scatter plot, mapping petal length against sepal width, with points colored by species and accompanied by a color legend. Built with React and D3 v5, it uses d3.scaleLinear for the x and y axes and d3.scaleOrdinal for the categorical color encoding. The SVG rendering separates axis, legend, and mark components, with circle elements representing each flower. Data is loaded asynchronously via d3.csv from a GitHub gist, and tick formatting uses d3.format for compact notation.
