Title: Remove use of arguments.callee that causes  strict violation when concat & minify

Fixes the following problem:
If you minify and concat nvd3 with any other files that have a global strict mode (as opposed to function-level), the whole minified file will be strict mode, and arguments.callee violates stict mode.
