This interactive scatter plot visualizes the Iris dataset, cycling the x-axis through four flower measurements while keeping petal width on the y-axis. It uses d3.csv to load the data, d3.scaleLinear for axes, and d3.axisBottom and axisLeft for grid lines. SVG circles are colored by species—orange, blue, and black—with a static legend and rotating axis labels via setInterval. The reusable scatterPlot function manages the chart structure and updates.
