This example displays the text “hello” on a bare HTML page, serving as a minimal starter template. It loads the D3.js library version 5 from a CDN via a script tag and renders static content directly in the browser. The code does not include any data visualization or interactive logic; it simply demonstrates the basic setup for a React-based visualization project, as referenced in the accompanying README link. The rendering relies entirely on standard HTML parsing and D3’s inclusion, with no additional APIs or data sources invoked.
