This scatter plot visualizes the Iris Dataset, showing sepal length against petal length. Each point is colored by species using a categorical color scale from `d3.scaleOrdinal` with `d3.schemeCategory10`. The visualization includes labeled axes and a color legend for species identification. The implementation uses `d3.scaleLinear` for positioning, `d3.extent` for domain calculation, and the `d3.selection` API for declarative rendering. Data is loaded from a CSV file and parsed with `d3.csvParse`.
