Arrow size, legend and saving path

[ROMA96x]

Hello,

I have some problems doing the following things:

1. Saving the diagram in a specific path.
   I'm using the option filename to change the name of the file generated, but how can I choose the path where the image will be created?
   "diagram", show=false, filename="architecture_diagram"):

2. Changing the size of the line in an arrow.
   I've seen the Graphviz attribute "arrowsize" but this only change the size of the head of the arrow. What can I do if I want also to increase the bodyline of the arrow?

3. Add a legend
   I have tried this approach:

legend_text = (
"legend: \l"
"red arrow = incompability found \l"
"green arrow = compatible \l"
)

with Diagram(diagram_label, show=False) as diag:
    Node(label=legend_text, width="8", shape="plaintext", )

However, this Node appears overlapped to the rest of the diagram. Is there a way to fix his position to a certain area?
For example, on the top left of the image.

@ROMA96x I am a novice user of this module and do not have answers for questions 2 and 3. For question one, you can include the path in the filename, for example; filename="./images/architecture.png" will save the image in a folder named images, if it exists.

To change Edge() weight, use the penwidth attribute, e.g. Edge(penwidth="2.0").

See: https://graphviz.org/docs/attrs/penwidth/
