Research graphic organizers thoroughly. There are many graphic organizers out there, such as webbing, concept mapping, matrix or flow chart, to name a few. Pick the one you find most interesting or you feel closest to.
Introduce your thesis. Every essay has to begin with an introduction that entails a thesis. Figure out why the graphic organizer you choose works well and for what type of people or projects it's best suited. Construct your thesis around that.
Describe the graphic organizer. Explain to the reader how he should go about drawing the graphic organizer, what he should look out for and how it works.
Explain what kind of project the graphic organizer is best for. Graphic organizers are intended to be used for different means, like studying, organizing and writing. You should discuss this in your essay and introduce the circumstances your graphic organizer will work best in.
Describe the type of person that the graphic organizer will suit best. People have different ways of understanding and remembering things, so what works for one person might not work for another.
Keep your structure. The introduction should be followed by three to four paragraphs in which you discuss ideas that support or deny your thesis. Use the conclusion of the essay to sum up the most important things you wrote about in the body of the essay.
