This scatter plot visualizes the Iris Dataset, showing sepal length on the x-axis and petal length on the y-axis across three species of iris flowers. Each species is represented by a unique color, with a color legend identifying the categories. The visualization uses D3 v7’s `scaleLinear`, `scaleOrdinal`, `schemeCategory10`, `axisLeft`, `axisBottom`, and `selection.join` to render the plot, axes, and legend. Data is loaded and parsed from a CSV file using `csvParse` and fetched asynchronously.
