This example visualizes the Iris Dataset as a scatter plot, mapping petal length and width to the x- and y-axes and coloring each point by species (setosa, versicolor, or virginica). It uses D3.js v6 with a linear scale and axis generators (`d3.scaleLinear`, `d3.axisLeft`, `d3.axisBottom`) to render SVG circles. Data is loaded via `d3.csv` from a remote URL, with numeric fields parsed on ingestion. The plot is sized to the full window and includes custom tick styling.
