As noted by Kirk (2016), composition deals with the overall readability and meaning of the project.  A presentation and a presentation of data are not the same thing. Presentations of data have a specific data driven focus, similar to an upcoming assignment. A well designed presentation of data is an impressive display of good composition, when it is done right.

Find an example presentation of data on the web, made in the R programming language. Do not repost an example your peers have already posted.
Why is your example a superior demonstration of composition?
How well does it represent the process of changing raw data into knowledge?
When replying to a peer compare your example and their example presentation. 

Do not forget to reference the source of the presentation. List all references and all references shall have citations.
