How can I visualize a file?

A common first thing you might want to do is quickly glance at the numerical content of a data file. How you do this of course depends on the language you want to use. In each case, you'll need the HDF5 library installed (see the code tab). In python (with pytables installed), use display_songs.py. In Java, you can use the great tool HDFVIEW. MATLAB will also let you visualize the content, see for example the Matlab tutorial.
