This scatter plot visualizes the Iris dataset, mapping petal length and width on the x and y axes while coloring each point by species (setosa, versicolor, or virginica). The visualization uses D3 v6 APIs including `scaleLinear`, `extent`, `axisLeft`, and `axisBottom` to define scales and axes, rendering circles as SVG marks. Data is loaded asynchronously from a CSV file via `d3.csv`, and the chart fills the browser window, with tick labels styled at 24 pixels for readability.
