Semantik (formerly kdissert) is a mind-mapping application for KDE that helps creating documents such as reports or presentations.
Mind-maps are edited either as flat trees (linear view on the left) or in two dimensions (center). Each node on the map can be associated with tables, text, pictures or diagrams (bottom-left corner).
Maps are then converted to "flat" documents such as presentations or reports using document generators (bottom-right corner). This enables the rapid creation of technical documentation in the LaTeX, OpenOffice or Html format.
