This scatter plot visualizes the classic Iris dataset, mapping petal length against petal width and coloring each point by species (setosa, versicolor, or virginica). The chart uses an SVG canvas rendered with D3 v6, employing `scaleLinear` to map the data columns to pixel coordinates and `axisLeft`/`axisBottom` for the labeled axes. Data is loaded from a remote CSV via `d3.csv`, with the plot points drawn as fixed-radius circles. The code also attempts to scale point dimensions from sepal measurements, though only the constant radius is applied visually.
