i'm not sure what language you're talking about... the Mathematica Help docs are full of examples. check this Histogram page[1] and scroll down, check the Options section, Applications section, etc. that is a typical level of exemplification for a function like Histogram, and other functions are detailed as appropriate and the examples regularly showcase how to use various functions/functionality together.
i think what may have happened in your case is that you believed Mathematica was a math-specific tool (which it isn't) and so you didn't pay enough attention to the non-math aspects of the language, such as the basic API (for which there is replete documentation/examples in the Help docs, see for example [2]).
the most useful key in Mathematica is F1. click on anything, any symbol or function, and hit F1 to see the Help page for that item
