Guidelines:
- Focus on the data in the Venn diagram, not on its appearance.
- Provide the data in brief statements.
- Give a summary if one is immediately apparent.
- Include the caption only if it is not accessible from elsewhere in the text. In this example, the caption is part of the image file and is therefore only accessible as part of the description.
