This example demonstrates loading and parsing a CSV file from a GitHub Gist URL using D3 v5’s `d3.csv`, then displaying the file size, row count, and column count in an HTML page. The visualization itself is a static SVG containing three simple geometric shapes—two triangles and an ellipse—each filled with a distinct color, which serves as the visual output accompanying the data summary. The page uses a React-ready framework structure, with minimal embedded CSS for text styling and a centered layout.
