如果你需要图形可视化，那么Graphviz库就很适合你，如果Python可以，那么你只需要一个Python绑定库graphviz（它在内部使用DOT language表示）。
将Arango DB中的图表JSON输入graphviz进行渲染非常简单。
您可以根据自己的风格自定义它，添加标签、颜色，调整节点形状等等。
下面是一个简单的JSON示例：

from graphviz import Digraph

arango_graph = [
    {
        "edges": [
            {
                "_key": "6392826",
                "_id": "germanHighway/6392826",
                "_from": "germanCity/Hamburg",
                "_to": "germanCity/Cologne",
                "_rev": "_WmZ77pW--D",
                "distance": 500
            }
        ],
        "vertices": [
            {
                "_key": "Hamburg",
                "_id": "germanCity/Hamburg",

                "loc": [
                    45.76,
                    4.84
                ]
            }
        ]
    }
]

graph_name = 'amazing'

g = Digraph(graph_name, filename=graph_name, format='jpeg', engine='neato')
g.attr(scale='2', label='Look at my graph my graph is amazing!', fontsize='18')
g.attr('node', shape='circle', fixedsize='true', width='1')

for item in arango_graph:
    for vertex in item['vertices']:
        g.node(vertex['_id'], label=vertex['_key'])
    for edge in item['edges']:
        g.edge(edge['_from'], edge['_to'], label=str(edge['distance']))

# Render to file into some directory
g.render(directory='/tmp/', filename=graph_name)
# Or just show rendered file using system default program
g.view()

只有3行代码用于自定义，还有5行代码用于图形可视化渲染器。请注意，Arango Web UI不会渲染同一对节点之间的所有边，而graphviz会，您可以为每个节点设置不同的样式。
您需要安装graphviz库和Python绑定

第1步：安装库

• 假设您的计算机是Ubuntu：*

sudo apt install graphviz

第2步：获取Python绑定

pipenv install graphviz

• 如果您还没有使用Pipenv，可以使用良好的旧Pip进行安装：*

pip install graphviz

第3步：运行示例并享受
