In short, yes - it's possible to implement such a tool for Yocto.
BitBake has a dependency viewer GUI already, it uses a set of tables
rather than a graph of nodes - presumably because the graph is *very*
large once you get past a trivial build.
You can play with the depexp by invoking:
bitbake -g -u depexp some-build-target
Internally BitBake generates a data structure of the interdependencies
(the g switch) which by default outputs a graphviz .dot file.
The -u depexp tells BitBake to instead draw the data structure using the
depexp GUI (lib/bb/ui/depexp.py).
Extending this GUI to offer a graph view might be interesting, the
difficulty will be in helping folks navigate the enormous graph...
Regards,
Joshua
