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 (probably too complex to render easily).

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.
