Current version and API is in experimental stage. Property names may change.
The graph layouting can be used as a command-line tool and as a library.
To install the command-line tool:
go get -u github.com/loov/layout/cmd/glay
To install the package:
go get -u github.com/loov/layout
Minimal usage:
package main
import (
"os"
"github.com/loov/layout"
"github.com/loov/layout/format/svg"
)
func main() {
graph := layout.NewDigraph()
graph.Edge("A", "B")
graph.Edge("A", "C")
graph.Edge("B", "D")
graph.Edge("C", "D")
layout.Hierarchical(graph)
svg.Write(os.Stdout, graph)
}
See other examples in examples folder.
Currently the layout.Hierarchy algorithm output is significantly worse than graphviz. It is recommended to use graphviz dot, if possible.
