Pipeline Viz

The Issue

Vizualise the pipeline in a CUI environment like the terminal using basic utf-8 characters. Just adds a graphical flair!
A very primitive example could be -

            ┌---┐        ┌---┐         ┌---┐
	... |   |<-------|   |-------->|   |<--------  
	    |   |------->|   |<--------|   |--------->  ...
	    └---┘        └---┘         └---┘

The input graph woud have the following structure -

graph = \
{
    'node_1': ('node_2', ),
    'node_2': ('node_3', 'node_4'),
    'node_3': ('node_4', ),
    'node_4': None,
}
