This example displays a static SVG composition featuring a black ellipse overlaid by a triangular form, paired with a text summary of a dataset. The page loads CSV data from a GitHub gist using `d3.csv` and reports its size in kilobytes, row count, and column count. The visualization uses D3 v7 for data parsing, while React is not actively employed despite being listed in the framework metadata, and the SVG rendering is hardcoded in the markup.
