This scatter plot visualization displays the Iris dataset, showing the relationship between petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, and virginica). The chart uses d3.csv to load the data, d3.scaleLinear for axes, d3.extent to set domains, and d3.axisLeft/axisBottom for rendering ticks. The SVG circles are positioned using the scaling functions, while the code also parses sepal measurements though they are not plotted. Axis labels appear rotated and positioned manually, with the visualization rendered entirely as SVG in a full-window viewport.
