Appendix I - Drawing Charts

A chart represents something as simply as possible. You don't have to be an artist to draw a diagram, but you should follow these few basic rules:

-Equip yourself with a sharp-pointed pencil and a ruler
And an eraser.
- Draw diagrams, large enough to show details easily.

The lines must be single and complete to give a clear image.

- Lines must complete an integrated structure without leaving out
Gaps, going too far unnecessarily, or blocking passages.

- The use of colors or shadows should not be used except to highlight important features.

- Charts need a clear title.

- The sign must be used to indicate the names of the things shown.

Footnotes are used to give a brief description of the parts mentioned.

- Tags and footnotes must be arranged horizontally around the frame
External chart.

The lines drawn with a ruler must precisely connect the marking, footnotes, and the indicated parts.

- Marking lines and margins must never intersect.

Note that a good diagram is often more valuable than a lengthy description.
