This scatter plot visualizes the Iris dataset, mapping sepal length on the x-axis and sepal width on the y-axis, with each of the three species (setosa, versicolor, and virginica) distinguished by a distinct fill color (skyblue, orange, and lightgreen). The visualization is built with D3 v6, using `d3.csv` to load the data, `d3.scaleLinear` for both axes, and `d3.axisBottom` and `d3.axisLeft` for rendering the scales. Data points are drawn as SVG circles, positioned via the scales, with the plot sized to the full browser window. The HTML also includes a centered, red, italicized and underlined title.
