The dottex package allows you to encapsulate ‘dot’ and ‘neato’ files in your document (dot and neato are both part of graphviz; dot creates directed graphs, neato undirected graphs). If you have shell-escape enabled, the package will arrange for your files to be processed at LaTeX time; otherwise, the conversion must be done manually as an intermediate process before a second LaTeX run.
