This example displays a summary of a cleaned Walmart dataset, showing a text message with the file size, row count, and column count alongside a static image of a Walmart store. The visualization uses React with hooks (`useState`, `useEffect`) to fetch the CSV data from a GitHub gist, parses the raw text by splitting on newlines and commas, and computes the dataset dimensions. The code relies on the native `fetch` API to retrieve the data, and renders the message and image using React DOM. The image is sourced from a New York Times URL, and the layout uses inline styles for centering and spacing.
