This scatter plot visualizes the relationship between sepal length and sepal width of Iris flowers, with each point colored by species (setosa, versicolor, or virginica) and accompanied by a legend. The visualization loads tab-separated Iris data via `d3.tsv` from a raw GitHub gist and renders it as an SVG using a reusable `ScatterPlot` module. It employs `d3.scaleLinear` for both axes, `d3.scaleOrdinal` for species colors, and `d3.axisBottom` and `d3.axisLeft` for labeled axes with a custom title.
