This example visualizes the HTTP request and response headers exchanged when loading the Twitter profile page for @WebSciDL, showing how header fields and values are organized and compared. The React-based code uses the Gist’s embedded JSON data to render the headers as a structured, hierarchical tree or table, likely leveraging a library like `react-json-view` or custom components to display nested objects and arrays. It highlights details such as status codes, content types, security policies, and cookie attributes from the captured network traffic, making the raw header data more readable and navigable.
