A scatter plot visualizes the classic Iris Dataset, showing sepal length against petal length for 150 flowers across three species. Circles are plotted without color or legend, with fixed 10-pixel radii. The visualization uses d3-fetch’s `csvParse` to load and parse the data, d3-scale’s `scaleLinear` for axes, and d3-axis’s `axisLeft` and `axisBottom` for labeled axes. The implementation is modular, with separate files for axes, scatter plot, and main visualization logic.
