This visualization shows a scatter plot of the Iris dataset, mapping petal length and width for each flower sample, with points colored by species (setosa, versicolor, or virginica). The code loads the data via D3’s `csv` from a GitHub gist, parses numeric fields, and uses `scaleLinear` with `extent` to set x–y domains. It renders SVG circles via `selectAll` and `join`, and appends an axis on the left and bottom using `axisLeft` and `axisBottom`. The chart also includes rotated axis labels.
