In preparing a presentation that incorporates external data, it is crucial to provide proper citations to ensure the information is credible and verifiable. This includes the publisher and the date of publication of the source. So, the piece of information that must be included with the graphic is its publisher and date of publication.
Including this information helps to:
1. Validate the Data: The audience can trust the information if they know it comes from a reliable source.
2. Trace the Source: Others who are interested can find the original data for further reading or verification.
3. Academic Integrity: Giving credit to the original author or publisher is an ethical practice in any academic or professional setting.

Therefore, its publisher and date of publication is the crucial information that must be included.
