This scatter plot visualizes the Iris dataset, mapping petal length and width for three species of iris flowers. The D3.js v6 code loads the data from a CSV file, scales the axes with `d3.scaleLinear`, and renders circles filled with distinct colors (skyblue, lightgreen, orange) per species. It uses the `d3.extent` and `d3.nice` functions to compute axis domains, and emits SVG axes via `d3.axisLeft` and `d3.axisBottom` with rotated axis labels.
