Working dir should be the project folder and not the root folder for graphviz/dot

[dspaeth-breuni]

Observed vs. expected behavior

When I try to create a graph with graphviz and use an image for the node, with a relative path within my project, then the image is not displayed.

This happens because the working dir is / instead of the project folder.

When I use the full path from root, for instance image="/User/demo/IdeaProjects/project/assets/pod.png", then the image is displayed.

Steps to reproduce

No image shows up:

:graphvizdot: /opt/homebrew/bin/dot
[graphviz, "demo"]
---------------------------------------------------------------------
digraph "demo" {
	"5926cd0c520a4b8f84cc092088e27a46"	[height=1.9028,
					image="./assets/pod.png",
					label="",
					pos="392.5,1315.5",
					shape=none,
					width=1.4028];
	
}
