Visualization of Process graph

[mathisrichter]

• Nice to have
• For debug, understand network

User story

As a user I want to be able to easily retrieve and visualize the process graph configured in Lava. It should be possible to include the values of chosen variables in the visualization, e.g., shape.

Conditions of satisfaction

• A method similar to process.run(), e.g. process.graph(), gives you a tabular overview of the process graph.
• A method to plot the process graph

Acceptance tests

• Configure a process graph in lava, retrieve the tabular process graph and check if it is the same.
