Typing into a text input updates an overlay of outlined boxes and arrows that segment the text into individual words, showing the word boundaries and their spacing. The visualization uses a hidden SVG layer synchronized with the input element’s rendered text, calculating character width from a monospace font. It is built with D3 selections and event handlers, rendering rectangles and text elements in SVG while reading the current input value on each keystroke.
