dot file error

[randfb]

I ran manually_generated_complex_diagram.py and it finished without error.
I tried to edit the output dot file with bpmn.io and got the error;

Text data outside of root node.
Line: 35
Column: 1
Char: }

I am not sure if bpmn.io supports the DOT syntax. Use generated XML file (manually-generated-complex-output.xml) instead.
