Visual programming uses some form of graphical interface for coding instead of a text-based porgramming language. Some, such as the children's coding tool Scratch, are close to textual programmong, but using techniques such as coloured lego-like blocks that slot together. Others, such as MAX heavily used in audio and the arts, use box-and-arrow data flow-style representations.
