 Instead of `graphviz-java` there are two alternative dependencies that can be used: 
 - `graphviz-java-all-j2v8` additionally contains dependencies to _all_ `J2V8` platforms. 
     So the same application can run on Linux, Mac OS X and Windows.  
 - `graphviz-java-min-deps` contains only dependencies that are absolutely necessary. 
-    All other dependencies are marked as `optional` and must added manually. See the [pom.xml](blob/master/graphviz-java-min-deps/pom.xml) for details.
