This scatter plot visualizes the Iris dataset, plotting petal length against petal width for individual flowers, with points colored by species (brown for setosa, orange for versicolor, red for virginica). The visualization uses D3.js v6, employing `scaleLinear` and `extent` to map data ranges to screen coordinates, and renders circles as SVG marks via `selectAll` and `join`. Axes are generated with `axisLeft` and `axisBottom`, while the data is loaded asynchronously from a CSV URL using D3’s `csv` function.
