This scatterplot visualizes the Iris dataset, mapping sepal length on the x-axis and sepal width on the y-axis for three iris species. Using D3 v7, it renders SVG circles with an ordinal color scale distinguishing setosa, versicolor, and virginica. The chart includes labeled axes, a descriptive title, and a legend. Data is loaded asynchronously via `d3.csv` from the provided GitHub URL, with linear scales (`d3.scaleLinear`), axes (`d3.axisBottom`, `d3.axisLeft`), and circle elements positioned by data attributes.
