This scatter plot visualizes the Iris Flower Dataset, mapping sepal length on the x-axis and petal length on the y-axis. Points are colored by species—blue for setosa, yellow for versicolor, and red for virginica—using filled circles rendered as SVG elements. Built with D3 v6 and React, the visualization uses `d3.csv` to load data from a GitHub Gist, `d3.scaleLinear` for continuous axes, and `d3.axisLeft` and `d3.axisBottom` to draw labeled axes. The plot dynamically sizes to the browser window.
