Make sure to have Graphviz installed in your system.

Graphviz (the tool is called dot) generates SVG and PNG images from dot files.

In this example, the computational graph is serialized in this format in order to represent it graphically. Note, however, that spaGO does not need Graphviz to work.

Run this from the current directory:

go run main.go | dot -Tsvg > example.svg

Enjoy ;)
