Python Streamlit st.graphviz_chart用法及代码示例

使用dagre-d3 库显示图表。

函数签名

st.graphviz_chart(figure_or_dot, use_container_width=False)

参数	说明
figure_or_dot (graphviz.dot.Graph, graphviz.dot.Digraph, str)	要显示的 Graphlib 图形对象或点串
use_container_width (bool)	如果为 True，则将图表宽度设置为列宽。这优先于图窗的原生 `width` 值。

示例

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)

或者您可以使用 GraphViz 的 Dot 语言从图表中渲染图表：

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
    }
''')
