This scatter plot visualizes the Iris dataset, showing sepal length on the x-axis and petal length on the y-axis, with each of the three species distinguished by color. The visualization uses D3 v7's scaleLinear for positioning, scaleOrdinal for categorical coloring, and the axisBottom and axisLeft components to create labeled axes. A separate color legend, built with custom SVG elements, maps each species to a specific color using a switch statement. Data is loaded from a local CSV file and parsed with d3.csvParse before being rendered as circular marks.
