This example displays a large black-and-white heading reading “카이제곱” above the text “Hello HTML,” with the body styled in huge 13em font and centered alignment. It uses plain HTML and CSS for layout and styling, while JavaScript performs a simple alert popup on load via java.js and logs “Hello JavaScript!” to the browser console. The page demonstrates a minimal static text visualization without data-driven graphics or interactive charts, relying solely on basic DOM elements and inline script execution.
