This example displays metadata about a dataset loaded from a CSV file, showing its size, row count, and column count. The page uses d3.csv to fetch and parse the data, then d3.csvFormat to calculate the file size in kilobytes. A static SVG illustration depicts a geometric mountain scene with a flag and building. The visualization combines a simple React-free HTML document with inline CSS styling and D3.js v7 for data loading and summary generation.
