Students worry about how to describe diagrams, but the basic method is always the same: introduction, summary of main points, specific details.
Look at the following question for example:
The diagrams below show some principles of house design for cool and for warm climates.
Although this question is different from the normal graph/chart questions, you should structure your answer in the same way. Try to write 4 paragraphs:
- Introduction: paraphrase the question.
- Summary: describe the main differences - the design of the roof and windows, and the use of insulation.
- Details: compare the roof design and use of insulation.
- Details: compare the window design and how windows are used during the day and at night.
