Block diagrams are widely used by engineers for controls, signal processing, communications, and mechatronics. A scale diagram is an accurate drawing of something that is usually much smaller than the original object. These diagrams may describe a sequence of independent events (for example a set of a coin tossed) or conditional probabilities (like drawing cards from a deck, without substituting the cards). Segments in a divided bar represent a set of quantities according to the different proportion of the total amount. LaTeX allows you to develop visuals and diagrams using various packages for this purpose.
