Understanding an intricate principle typically requires us to hold multiple concepts in mind. Visual Representations (diagram/graph/image) assist in doing precisely that. Remember how we were taught ‘resistance’ in Science classes? We still remember representing ‘resistance’ by a wavy line that intended to show ‘disturbance’. Don’t we? Utilizing a graph method, a complicated idea might be condensed into an easy to understand representation, makings it a lot easier to connect to the principle and remember it.
