Ascii DAG for visualization of dataflow

stacked-dag can show Ascii-DAG(Directed acyclic graph) from a Dot file of graphviz. Dataflow's direction is from top to bottom. 'o' means a node. A label of the node is shown to the left side. Other characters are edges of DAG.

A sample of DAG is below.

o o    l0,l4
|/
o    l1
|
o    l2
|
o    l3

Usages

Write a Dot file of graphviz.

$ cat > sample.dot
digraph graphname {
  0 [label="l0"];
  1 [label="l1"];
  2 [label="l2"];
  3 [label="l3"];
  4 [label="l4"];
  0->1;
  1->2;
  2->3;
  4->1;
}

Show ascii DAG by following command.

$ stacked-dag dot sample.dot
o o    l0,l4
|/
o    l1
|
o    l2
|
o    l3
