This scatterplot visualizes the Iris dataset, showing sepal width against sepal length for three species of iris flowers. Each flower is represented by a colored circle, with species assigned distinct colors from a d3.scaleOrdinal range. The visualization is rendered as an SVG using D3 v6, with d3.scaleLinear functions mapping the measurement domains to pixel coordinates for the axes. The plot is constructed by appending a group element, adding axis generators d3.axisLeft and d3.axisBottom, and binding the data to circle elements.
