This is some code to create a WLED LED-Map (the JSON that tells WLED the positions of the LEDs) with some features that I didn't find in any online editors: Dragging the mouse over the canvas fills all hovered cells, rescaling the map to a different size, inverting, and inserting LEDs in between existing ones.
