Grapher issue: Error: <gvedit>: syntax error in line 3 near ','

I used Guice's grapher to print .dot file (which dump dependency graph from xtext), and attempt to use graphviz to open it.
But the error occured:
Error: : syntax error in line 3 near ','

I installed graphviz-2.38.0, use guice com.google.inject_3.0.0.v201605172100.jar and guice-grapher-3.0.jar (from mvnrepository.com). My OS is windows7.

The .dot file looks good, is it possible because I am using the wrong Graphviz version?
Does anyone have the same problem as me? Or anyone can open this attachment file?
Thanks.
