This scatter plot visualizes the Iris dataset, plotting petal length on the x-axis and petal width on the y-axis, with each point colored by species (setosa, versicolor, or virginica). The chart uses D3 v6 with SVG rendering, employing `d3.csv` for data loading, `scaleLinear` for scales, and `axisBottom`/`axisLeft` for axes. The code also references sepal measurements for potential alternate encoding, though only petal dimensions are displayed with circles. Data is sourced from a GitHub-hosted CSV file.
