Final answer:
Diagrams can show various types of information such as relationships between variables, trends, proportions, and specific examples of concepts, using formats like line graphs, pie charts, and bar graphs.
Step-by-step explanation:
Diagrams are versatile tools that can show a variety of information. They often illustrate patterns, comparisons, trends, and apportionment. For example, a line graph can display the relationship between two variables, with one on the horizontal axis and one on the vertical axis. A pie graph may be used to depict how a whole is split into several parts, with each slice representing a percentage of the total. Bar graphs utilize the height of bars to show relationships and can also show subgroups within each bar.
Diagrams can indicate the parts of an object or cycle, provide specific examples of a concept, show the changes in data from year to year, or delineate the exact way something moves. They serve as a method of presenting numerical data visually to convey an intuitive sense of the relationships within the data.
