This visualization presents a scatter plot of the Iris flower dataset, loaded from a CSV file hosted on GitHub Gist. The example demonstrates the basic setup for a D3.js visualization within a minimal HTML page, using the d3.v7 library. It constructs the CSV URL by joining several string parts, including the gist URL, username, gist ID, commit hash, and file name, then logs the resulting URL to the console. This serves as a starting point for building interactive scatter plots, though the current code only prepares the data source without rendering any visual elements yet.
