Doodle diagrams are a flexible, creative way of visualizing ideasâespecially useful for programmers before formal mindâmaps or concept maps take shape. By sketching everything from many angles with markers, they let you break down complex interfaces into simple building blocks; the author shows this by dissecting LMMSâs song editor into just two elementsâthe time track and draggable rectanglesâto make a small clone in JavaScript and Svelte. The post also argues that doodle diagrams help clear scattered thoughts and relieve workârelated stress, encouraging developers to keep notebooks full of colorful sketches as they craft side projects or launch their own startup, while pointing out useful online tutorials for JS, Svelte, and LMMS.
