The ability to add Graphs to word documents

I have recently been trying to build an automated customer report that creates a 20 odd page report that includes paragraphs, images and values in currency in different visual representations in shapes and so forth.

I would love the ability to add graphs in too such as pie and bar graphs so that it can loo even more professional. I was advised to create different documents (in excel and word) and merge them so when I get to the paragraph page i format it in the same way as word and then create 2 (or more) docs in doc gen), the problem with this is that I am not always sure what page these will be on depending on the data/info in other pages, also I would have to somehow dynamically adjust the page numbers across 2 different documents but also for my current report it would be about 10 different documents I would have to create and merge. We really need an easy way to create graphs in word please
