This example summarizes a study focus dataset by displaying its file size, row count, and column count in a styled React interface. The app fetches a remote CSV file from a GitHub gist and uses D3’s `csvParse` method to parse the text, then presents the metrics alongside a simple SVG containing a circle and rectangle. The visualization relies on React’s state management (`useState`) and `fetch` API, with D3 v7 loaded via script, and renders text and shapes using standard SVG markup.
