Anyway, I'd say that the expression 'graphic organizer' acts as an 'umbrella term' for various forms of organizing information through charts and diagrams, whereas 'mind map' stands for a particular format of classifying data.
A mind map is a diagram used to represent words, ideas, tasks or other items linked to and arranged radially around a central key word or idea. It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, and decision making. en.wikipedia.org/wiki/Mind map
A graphic organizer is a visual representation of information in an organized manner that is intended to enhance understanding (eg, Venn diagram, T-graph, word web, KWL chart) www.instech.tusd.k12.az.us/Core/glossary/writeglossary.doc
