This visualization uses D3.js v6 to render a scatter plot of the classic Iris dataset, mapping petal length on the x-axis and sepal length on the y-axis. Each circle represents a sample, colored by species (black for setosa, blue for versicolor, red for virginica). The code loads CSV data from a GitHub gist, uses `scaleLinear` and `extent` to compute scales, and renders SVG circles with axis labels, employing `axisLeft` and `axisBottom` for the chart axes.
