This scatter plot visualizes the Iris Dataset, showing the relationship between sepal length and petal length across three species of iris flowers. The visualization encodes each observation as a circle positioned by two quantitative axes, with species differentiated by color coding. Built with D3 v5, the example employs `d3.scaleLinear` for axis scaling, `d3.extent` for domain calculation, and `d3.axisLeft`/`d3.axisBottom` for rendering axes. Data is loaded and parsed asynchronously from a local CSV file using the Fetch API and `d3.csvParse`.
