The graphviz-Frontend is a web interface to Graphviz, the open source graph visualization software.
Compile the go binary:
go build web.go
Run the go server:
./web
Visit the website at: http://localhost:8080/
This webpage talks to the graphviz-api service and the endpoint of that defaults to http://localhost:8000/dot. If you are running it an environment where it is available at a different URL, you need to specify it as environment variable GRAPHVIZ_API_ENDPOINT.
For example, when running docker container:
-e GRAPHVIZ_API_ENDPOINT=http://1.2.3.4:8000/dot
