This example demonstrates a minimal React and D3 integration, rendering a simple “Hiya” message at the center of the page. It fetches a CSV file containing named CSS colors using `d3.csv`, though the data is not visualized. The code combines `d3.v7`, React, and ReactDOM within a single HTML file, with the React component defined and mounted via `ReactDOM.render`. The page uses large, 13em text styling to emphasize the greeting, highlighting a basic setup for future data-driven visualizations.
