This visualization displays the classic Iris dataset as a scatter plot, mapping petal length on the x-axis against sepal length on the y-axis. Each circle represents an individual flower sample, with tooltips revealing its exact coordinates. The code uses d3.csv for data loading, d3.scaleLinear for both axes, and d3.axisBottom and d3.axisLeft for tick marks. All points are rendered as SVG circles, with the canvas sized to fill the browser window.
