This example documents the keyboard shortcuts available in the VizHub editor, presenting them in a Markdown table within the README. The visualization itself is a minimal HTML page that displays only the title and the word "README" with large, centered typography. The code relies on standard HTML and CSS for styling, while the documentation references CodeMirror and VIM key bindings, including commands like toggling comments and killing lines. It does not use any data visualization libraries, instead serving as a static reference chart.
