The text that may accompany each diagram presents a brief integrating overview of the diagram, citing important relations, patterns, or subtle interactions between the boxes and arrows.
Preferably, the text is less than a page in length. It highlights features that the author feels are of special interest or significance by walking the reader through the main ideas of the diagram. It does not duplicate every detail shown on the diagram itself.
Write the text only after a diagram has received a fairly high level of review and approval. Waiting to write the text forces the diagram itself to properly communicate the intended message. Text based on carefully drawn diagrams will be as structured and as organized as the diagram itself.
Use glossary definitions to summarize the special meanings that may arise for key terms, words, phrases and acronyms used in the diagram. A word or phrase may have different connotations for different readers of the diagram.
