This scatterplot visualizes the Iris dataset, plotting sepal width against sepal length for three flower species. The D3.js chart uses separate colors for setosa, versicolor, and virginica, with circles for each data point. Interactive tooltips display species and values on hover, while an axis legend identifies the species. Built with d3.v7, it loads CSV data from a remote URL and uses scaleOrdinal for colors and scaleLinear for axes. The SVG rendering includes a responsive layout that adjusts to window size, with axes, labels, and a legend.
