This scatter plot visualizes the sepal length and sepal width measurements from the Iris dataset. Each data point is represented as a purple circle, plotted using D3 v7's `scaleLinear` and `extent` functions to map the numeric values to the SVG canvas. The chart includes labeled x and y axes, created with `axisBottom` and `axisLeft`, and is rendered as an SVG. The data is loaded from a local `iris.csv` file using D3's `csv` method.
