Hi,
Basically, I've made a line graph that describes the number of papers published in the last few years relating to a topic. I took the number of papers from PubMed (using the download tool in the filters section).
I understand that I will have to reference it somehow, as I did not create the original data - I just made it into a graph for better visuals for my coursework.
How would I reference this? My university uses Harvard referencing, btw. Thank you x
