This example demonstrates how to load and summarize a local CSV dataset within a web page. It displays a static SVG diagram and prints a message with the dataset’s file size, row count, and column count using D3’s `d3.csv` and `d3.csvFormat`. The page also highlights ES6 module imports through `import { select } from 'd3'` and a custom `myMessage.js` module, with styling defined in an external CSS file.
