I have some lists of gene annotation come from the Gene Ontology. Every annotation is a coupling
<gene, feature> where the feature is a Gene Ontology term. Every term is a node in the Gene Ontology tree.
I need a tree visualization tool to depict the Gene Ontology tree of that term, and so understand in which tree level is the analyzed term.
Something like this picture:
Can you suggest a tree viewer software that could be useful to me to solve this issue?
Thanks a lot!
