This scatter plot visualizes the Iris dataset, mapping each flower’s specification values along the y-axis against keyword values on the x-axis, with points colored by CSS level categories (turquoise, orange, violet). The D3 v5 code loads CSV data via `d3.csv`, applies linear scales with `d3.scaleLinear`, and renders SVG circles with axes generated by `d3.axisLeft` and `d3.axisBottom`. A custom legend distinguishes the three CSS level groups, while axis titles and tick styling are applied through D3 selections.
