Free tool for graphical representations of XML files
Notepad++ does the trick.
Notepad++ is a free (as in "free speech" and also as in "free beer") source code editor and Notepad replacement that supports several languages.
Some more features
- Tabbed document interface
- Drag-and-drop
- Multiple Clipboard (plugin required)
- Split screen editing and synchronized scrolling
- Spell checker (requires Aspell) (Spell checker does not distinguish between text and code)
- Supports text encoding formats such as Unicode, for international writing systems
- Find and replace over multiple documents
- File comparison
- Zooming
- Syntax highlighting and syntax folding

I recommend the free XML Marker version 1.1 - download link (not the latest commercial version). Although version 1.1 has not been updated since 2004, it is still entirely sufficient for most purposes.
