Subject: [PATCH] Fix issue in python sample source in Tutorials.md

Updated python sample source in Tutorials to make it work. Before this change problem was:

```
C:\Users\user>python mermaid.py
Traceback (most recent call last):
  File "mermaid.py", line 3, in <module>
    graphbytes = graph.encode("ascii")
NameError: name 'graph' is not defined
```
