This example displays a summary of CSV data, showing the computed file size in kilobytes, row count, and column count for a small inline dataset of employee records. The data is parsed using `d3.csvParse` on a hard-coded string, and a Blob object calculates the approximate file size. The interface presents these three metrics inside a styled white box with a hover-scale effect, set against a blue gradient background. D3.js v7 handles the CSV parsing while standard browser APIs manage the file-size estimation.
