What relationship does my target audience have with the piece of info graphics?

Nurses and Doctors would have first started a relationship with a piece of info graphics displaying how much air we breathe in a lifetime when they were training/learning for the job.

A teacher might also have seen it whilst learning for the job, however they might have first seen if when it had been introduced to their syllabus they have to teach.

Pupils/students would have first seen it when their teacher showed it to them, or by researching (books/internet).

The audience interacts with the product by reading it, and taking in information.
I would imagine the piece would be found in schools, colleges, libraries, and in doctor’s surgeries/hospitals.
