Here is something for KCachegrind:

======================================
For developers to get more inside into the runtime characteristics of
their own or other's programs, KCachegrind can help quite a lot
(homepage: http://kcachegrind.sf.net). It's a visualization frontend
for profiling data, i.e. it allows you to see the execution flow and 
distribution of time spent in functions. Though written in C++ with KDE libs, 
it's not bound to inspect C++ code, but only bound to the data a profiler 
tool delivers.

Currently, profile data from Calltree (see kcachegrind.sf.net) and Cachegrind,
both using the runtime instrumentation framework Valgrind 
(http://developer.kde.org/~sewardj/), is supported. This enables you to 
profile unmodified binaries on Linux/X86, including shared libraries and 
dynamically opened plugins.

Visualisations featured by KCachegrind are among others the unique treemap 
view and interactive call-graph view. For more insight, annotated source
and annotated disassembler is provided.

KCachegrind, together with Calltree, is already used quite often to
detect performance bottlenecks in KDE libraries and applications,
and waits to look at your own applications!
==========================================

For a screenshot, best use the one from the KCachegrind main page.
And as a new Konqueror plugin, you forget to mention the FSView KPart (or is 
this an added Konqueror feature?!):

===========================================
Konqueror now has a new, graphically appealing way of browsing your 
directories: As an alternative to the icon and list view modes for 
directories, the FSView KPart from the kdeaddons package can show
you the hierarchy of all subdirectories by using nested rectangles for files
and directories. Using rectangle areas proportional to file sizes, it's easy
to spot the largest harddisc space wasters even deep down in the directory
hierarchy. As the FSView Part acts as full replacement to the other
view modes, it opens files and directories by clicking on them, and features 
the standard KDE file context menu, e.g. for the direct deletion of large 
files. Look into the View menu for options to change the visualization in 
various ways. In addition, FSView is available as a standalone application.

Some background info: The FSView KPart originated in a small usage demo for 
the treemap widget class, developed for KCachegrind. While still consisting 
of only a few hundred lines of code in addition to the treemap widget, it 
shows the power of the Konqueror and KPart architecture.
=============================================

Thumbnail Screenshot of FSView attached.
