This visualization displays the Iris dataset using a scatter plot, mapping petal length on the x-axis and petal width on the y-axis. Each point is colored by species (setosa, versicolor, virginica) using skyblue, lightgreen, or orange. The code loads CSV data from a GitHub repository via `d3.csv`, scales axes with `d3.scaleLinear`, and renders SVG circles with `d3.selectAll` and `data.join`. Axis labels are added using text elements, while `d3.axisLeft` and `d3.axisBottom` generate the tick marks.
