This example displays a minimal static web page showing the text “Hello HTML!” centered in the browser window. The page includes an HTML file, a CSS stylesheet, and a JavaScript file that simply logs “hello world” to the console. It uses no external libraries or data sources, only plain HTML, CSS, and JavaScript to demonstrate the basic structure of a web-based project. The file appears to be a starter template for building a data visualization, but the current version contains no visualization code or interactive elements.
