Drawing a simple Mind Map
Figure 1: An Example of Mind Map

To make notes on a subject using a Mind Map, draw it in the following way:
Write the title of the subject you're exploring in the center of the page, and draw a circle around it. This is shown by the circle marked 1 in Figure 1, above.
As you come across major subdivisions or subheadings of the topic (or important facts that relate to the subject) draw lines out from this circle. Label these lines with these subdivisions or subheadings. These are shown by the lines marked 2 in Figure 1.
As you "burrow" into the subject and uncover another level of information (further subheadings, or individual facts) belonging to the subheadings above, draw these as lines linked to the subheading lines. These are shown by the lines marked 3 in Figure 1.
Finally, for individual facts or ideas, draw lines out from the appropriate heading line and label them. These are shown by the lines marked 4 in Figure 1. As you come across new information, link it in to the Mind Map appropriately.
A complete Mind Map may have main topic lines radiating in all directions from the center. Sub-topics and facts will branch off these, like branches and twigs from the trunk of a tree. You do not need to worry about the structure produced, as this will evolve as you develop your mind map.
Note that the idea of numbered 'levels' in Figure 1 is only used to explain how the Mind Map was created. All we are showing is that major headings radiate from the center, with lower level headings and facts branching off from the higher level headings.
