You can view a treemap of subroutine exclusive time, grouped by package.
NYTProf also generates call-graph files in Graphviz format: inter-package calls, all inter-subroutine calls.

You can hover over some table cells and headings to view extra information.
Some table column headings can be clicked on to sort the table by that column.
