This visualization displays the text "Hello World!" in a large, monospace font centered on a blank SVG canvas. It uses D3 v4 to select the page body, append an SVG element with fixed dimensions of 960 by 500 pixels, and add a single text element with a font size of 36 pixels. The text is positioned at coordinates (120, 200) using the `attr` method for both x and y placement. No data source or interaction is present; it simply demonstrates the basic setup of a D3 SVG rendering environment.
This example demonstrates the Fibonacci sequence through a custom JavaScript iterator. The code defines an object with a `[Symbol.iterator]` method that generates successive Fibonacci numbers, logging each value to the console. A `for...of` loop consumes the iterator and breaks once a value exceeds 50, triggering the iterator’s `return` method to log "finished---". The example uses native JavaScript iteration protocols rather than any external libraries, with console output as the only visualization.
