The following phrase has been taken from Wikipedia's computer science style guides:
Samples of actual source get included in articles for a variety of reasons, although the most typical reasons are to demonstrate the "look" of a particular language, to provide examples of language-specific constructs or features, and to provide examples of algorithms not easily expressed in pseudocode.
What is the meaning of the 'to demonstrate the "look" of a particular language'?
I have two variants:
-
to demonstrate particular language's point of view, approach, which is more at the logical level, than just visual representation
-
to demonstrate how something (visually) looks like when written in a particular language. In this case "look" reminds of "look and feel"
Or maybe neither variant is good.

"look" of a particular programming language refers to snapshot of the structure, basic constructs and syntax. Usually "hello world" program is used for every language to illustrate the same.
