This scatter plot visualizes the Iris dataset, showing petal length on the x-axis and petal width on the y-axis, with each point colored by species (green, purple, or red). It uses d3.csv to load the data, d3.scaleLinear for axes, and d3.axisLeft and d3.axisBottom to render the scales. Circles are drawn as SVG elements via a data join, with labels for the axes in red and purple. The plot is rendered in vanilla HTML.
