Hi,

I added a new control TLvlGraphControl to package LazControls. It is a
LCL control showing a graph as "level graph". Another name is "layered
graph".

See the screenshot and see here:
http://wiki.lazarus.freepascal.org/Lazarus_1.2.0_release_notes#TLvlGraphControl

Level graphs can visualize hundreds of nodes and thousands of
edges on a single screen, reducing the need to scroll.
This control has the ability to highlight the edges under
the mouse, so that even complex graphs with thousands of edges can be
explored.
And it highlights back edges so you can quickly find cycles.

The screenshot is from the IDE's Package Graph.
