+### Helper Graphviz Graph Export
+- Visualising graph could be useful to see the dependency problem, therefore helper `generateModulesGrapvizText` is included.
+- By default it generates graph of all modules in a project.
+- Longest path of the project is in red.
+- Adding parameter `modules.graph.print.statistics` prints also information about the graph.
+- You can set `modules.graph.of.module` parameter if you want only subgraph of total graph.
+```
+./gradlew generateModulesGrapvizText -Pmodules.graph.print.statistics=true -Pmodules.graph.of.module=:feature-one
