This visualization shows the classic Iris flower dataset as a scatter plot, mapping sepal length on the x-axis against petal length on the y-axis, with each of the three species distinguished by different symbol shapes from d3’s symbolsFill. A legend on the right identifies the species-shape mapping using d3.scaleOrdinal with shapeSymbol generator. The chart fetches the iris.csv data from GitHub, parses it with d3.csvParse, and renders the plot using d3.v7’s select, scaleLinear, axisBottom, and axisLeft, with axes fitted via the axes.js helper module.
