This example creates a scatter plot from the classic Iris dataset, loading the CSV data from a GitHub gist. The chart is built as a reusable `ScatterPlot` class using d3.v7's `scaleLinear` for coordinate mapping and `axisLeft`/`axisBottom` for axes. The SVG visualization is appended to the page body with dimensions set to the full window size. Notably, the core plotting logic is commented out, so the example demonstrates the structure of separating data fetching and chart construction without rendering the actual points.
