# Tutorials

This is  list of publicly available Tutorials for using Mermaid.JS . This is intended as a basic introduction for the use of the Live Editor for generating diagrams, and deploying Mermaid.JS through HTML.

For most purposes, you can use the [Live Editor](https://mermaid-js.github.io/mermaid-live-editor), to quickly and easily render a diagram.


## Live-Editor Tutorials
The definitions that can be generated the Live-Editor are also backwards-compatible as of version 8.7.0.

## 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.

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

graph = """
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)
```

**Output**
