Create report diagram for number of fields per content type

Hii,

I have created MR !24 as per my understanding. Kindly review and let me know the changes.
Thanks!

Nice work @nidhi27. Thank you for the contribution. I made some changes to the wording on some of the titles, labels and headings.

Visually the diagram can easily have is key and title escape its bounds. That is a problem unrelated to this issue so we will ignore it for now and cover it with a separate issue.
