Here's a footnoted sentence from Bovee and Thill:

 For example, three-dimensional bar chart, cones, and pyramids can look appealing, but the third dimension usually adds no additional information and can be visually deceiving as well. 16

Here's the citation for the source:

16 "Pyramid Perversion -- More Junk Charts," Stubborn Mule blog, 12 March 2010, www.stubbornmule.com.

How would this look in MLA style?

 For example, three-dimensional bar chart, cones, and pyramids can look appealing, but the third dimension usually adds no additional information and can be visually deceiving as well (             ).


I want to quote this in my paper. Which source do I use?

" For example, three-dimensional bar chart, cones, and pyramids can look appealing, but the third dimension usually adds no additional information and can be visually deceiving as well" (            ). 

But which source SHOULD I use?

Taking notes? Be careful about paraphrasing and quoting -- be clear for yourself which you are doing, and which information comes from what source.
