This scatter plot visualizes the Iris Dataset, showing sepal length against petal length, with each point colored according to iris species. The visualization includes labeled axes and a color legend identifying the three species categories. Built with D3 v7, the code uses `scaleLinear` and `scaleOrdinal` for scaling, `schemeCategory10` for the color palette, and modular functions like `axes` and `colorLegend` to compose the chart. Data is loaded from a CSV file and parsed with `csvParse`.
