st.graphviz_chart - 显示Graphviz图表

streamlit的graphviz_chart使用dagre-d3库显示图表。

方法原型

streamlit.graphviz_chart(figure_or_dot, width=0, height=0)

参数：

• figure_or_dot：要现实的Graphlib图对象或dot字符串
• width：图表宽度像素数，0表示使用完整宽度
• height：图表高度像素数，0表示使用默认高度

示例代码

>>> import streamlit as st
>>> import graphviz as graphviz
>>>
>>> # Create a graphlib graph object
>>> graph = graphviz.DiGraph()
>>> graph.edge('run', 'intr')
>>> graph.edge('intr', 'runbl')
>>> graph.edge('runbl', 'run')
>>> graph.edge('run', 'kernel')
>>> graph.edge('kernel', 'zombie')
>>> graph.edge('kernel', 'sleep')
>>> graph.edge('kernel', 'runmem')
>>> graph.edge('sleep', 'swap')
>>> graph.edge('swap', 'runswap')
>>> graph.edge('runswap', 'new')
>>> graph.edge('runswap', 'runmem')
>>> graph.edge('new', 'runmem')
>>> graph.edge('sleep', 'runmem')
>>>
>>> st.graphviz_chart(graph)

你也可以使用GraphViz的Dot语法绘制图表：

>>> st.graphviz_chart('''
    digraph {
        run -> intr
        intr -> runbl
        runbl -> run
        run -> kernel
        kernel -> zombie
        kernel -> sleep
        kernel -> runmem
        sleep -> swap
        swap -> runswap
        runswap -> new
        runswap -> runmem
        new -> runmem
        sleep -> runmem
    }
''')

效果如下：
