This scatter plot visualizes the Iris dataset, encoding petal length on the x-axis and petal width on the y-axis, with each point colored by species (skyblue for setosa, lightgreen for versicolor, orange for virginica). The visualization uses d3.csv to load the data, d3.scaleLinear for both axes, and d3.axisLeft and d3.axisBottom to render the ticks. The SVG circles also carry sepal length and width values in their rx and ry attributes, though these do not affect the visual representation. The chart fills the full browser window with custom margins and labeled axes.
