我想使用sigma.js来显示一些DOT图。但似乎sigma.js只支持json图形格式。
是否有一些bash工具或javascript模块可以将DOT图转换为json图?
例如来自DOT图:
graph {
n1 [Label = "n1"];
n2 [Label = "n2"];
n3 [Label = "n3"];
n1 -- n2;
n1 -- n3;
n2 -- n2;
}

转移到JSON图:
{
"nodes": [
{
"id": "n0",
"label": "A node",
"x": 0,
"y": 0,
"size": 3
},
{
"id": "n1",
"label": "Another node",
"x": 3,
"y": 1,
"size": 2
},
{
"id": "n2",
"label": "And a last one",
"x": 1,
"y": 3,
"size": 1
}
],
"edges": [
{
"id": "e0",
"source": "n0",
"target": "n1"
},
{
"id": "e1",
"source": "n1",
"target": "n2"
},
{
"id": "e2",
"source": "n2",
"target": "n0"
}
]
}

如果您可以使用python并安装2个软件包(networkx和pygraphviz),这里有一个将点图转换为json图的简短脚本:
# dot_to_json_graph.py
# http://stackoverflow.com/questions/40262441/how-to-transform-a-dot-graph-to-json-graph
# Packages needed :
# sudo aptitude install python-networkx python-pygraphviz
#
# Syntax :
# python dot_to_json_graph.py graph.dot
import networkx as nx
from networkx.readwrite import json_graph
import sys
if len(sys.argv)==1:
sys.stderr.write("Syntax : python %s dot_file\n" % sys.argv[0])
else:
dot_graph = nx.read_dot(sys.argv[1])
print json_graph.dumps(dot_graph)
这是你的例子,转换为json图:
{"定向":false,"图":[["节点",{"标签":"& #34;}],[" graph", {" file":" test.dot"}],[" edge",{}],[" name",&#34 ;"]],"节点":[{" id": " n1","标签":" n1"},{" id":" n2",&#34 ;标签":" n2"},{" id":" n3", "标签":" n3"}],"链接":[{"来源":0,"目标" :1," key":0}, {" source":0," target":2," key":0},{" source":1,&#34 ;目标":1, " key":0}]," multigraph":true}

我无法在Windows和Linux中安装pygraphviz,而且我最近遇到了同样的问题。 networkx现在支持更容易地转储到json中,包括d3.js格式(info in this page)
我有两个解决方法:
1-使用PyDot
很快就会过时!由于我们在python中有graphviz接口,因此PyDot可能不会频繁使用。
def dot_to_json(file_in):
import networkx
from networkx.readwrite import json_graph
import pydot
graph_netx = networkx.drawing.nx_pydot.read_dot(file_in)
graph_json = json_graph.node_link_data( graph_netx )
return json_graph.node_link_data(graph_netx)
2-使用graphviz来源
如graphviz界面文档的this part所示,您可以从.dot源文件创建图表。
