gographer

Simple graph package for go. Uses d3js for visualization and websockets for communication.

Run the test visualization

go run test_graph/visualization.go

and visit localhost:8080 in your browser

Using it

Import it:

import "github.com/fjukstad/gographer"

Using it:

graph = gographer.New();
// (ID, NodeStringID, GroupName, Size)
graph.AddNode( 1, "NodeStringID", "GroupName", 1 )
graph.AddNode( 2, "NodeStringID", "GroupName", 1 )

// (Source, Target, EdgeID, weight )
grap.AddEdge( 1, 2, 0, 1 )
graph.AddEdge( 2, 1, 100, 15 )

graph.DumpJSON( "graph.json" )
http.ListenAndServe( ":8080", http.FileServer( http.Dir( "." ) ) )

Open localhost:8080 in a webbrowser to view the graph. Have a look at localhost:8080/canvas.html for the visualization using the HTML canvas element for rendering. Visit localhost:8080/cytoscape.html for a visualization using the cytoscape.js library.

Modify the d3js implementation and visualization to your preferences.
