This visualization displays the classic Iris dataset as a scatter plot, mapping petal length on the x-axis and petal width on the y-axis. Each of the 150 flowers appears as a colored circle, with species distinguished by hue: setosa in red, versicolor in green, and virginica in magenta. The chart uses D3 v6 APIs including `scaleLinear`, `extent`, `axisBottom`, and `axisLeft`, rendering as SVG. The code also retrieves the dataset via `d3.csv` from a GitHub gist, and the background is a bright blue.
