This scatter plot visualizes the Iris Dataset, mapping petal length and width on the axes while coloring each point by species (setosa, virginica, or versicolor). Built with D3 v6, it uses `scaleLinear`, `extent`, and `axisBottom`/`axisLeft` to generate the axes and `select` to append SVG circles with a fixed radius. The code also parses numeric fields from CSV data and applies a custom color marker for species.
