## Python Integration with mermaid-js
Here's an example of python integration with mermaid-js which uses the mermaid.ink service.
This is also working with colab and jupyter lab notebooks.
## Jupyter Integration with mermaid-js

Here's an example of Python integration with mermaid-js which uses the mermaid.ink service, that displays the graph in a Jupyter notebook.

```python
import base64
import requests, io
from PIL import Image
from IPython.display import Image, display
import matplotlib.pyplot as plt

graph = """
def mm(graph):
graphbytes = graph.encode("ascii")
base64_bytes = base64.b64encode(graphbytes)
base64_string = base64_bytes.decode("ascii")
display(Image(url="https://mermaid.ink/img/" + base64_string))

mm("""
graph LR;
A--> B & C & D;
B--> A & E;
C--> A & E;
D--> A & E;
E--> B & C & D;
"""

graphbytes = graph.encode("ascii")
base64_bytes = base64.b64encode(graphbytes)
base64_string = base64_bytes.decode("ascii")
img = Image.open(io.BytesIO(requests.get('https://mermaid.ink/img/' + base64_string).content))
plt.imshow(img)
""")
```
