Use of diagrammatic representations of circuit diagrams can aid understanding of principles of electricity. This diagrammatic representation illustrates a solution model to a given problem. An Euler diagram is a diagrammatic means of representing sets and their relationships. Extensive use is usually made of a diagrammatic style known as the block diagram. An Euler diagram (, ) is a diagrammatic means of representing sets and their relationships. The diagrammatic notation is useful in manipulating tensor algebra. The divisions proposed for the Archaeplastida are shown below in both tabular and diagrammatic form. Based on them are John F. Sowa's conceptual graphs and Sun-Joo Shin's diagrammatic reasoning. This spatial metaphor can be analysed by sociologists and realised in diagrammatic form. A diagrammatic representation can be found here. Some mathematical notations are mostly diagrammatic, and so are almost entirely script independent. Macaulay duration has the diagrammatic interpretation shown in figure 1. A diagrammatic explanation of copper copings is available. This is usually followed by a diagrammatic reformulation to amplify and reinforce the letter. The figure below shows this in a diagrammatic form.
