graphviz - Graphviz DOT 文件中的多个图形

Question

我有这个 Graphviz DOT 图:

digraph unit_test {
    label="Unit test"
    
    edge [fillcolor="#a6cee3" color="#1f78b4"]

    node[shape="ellipse" style="filled" fillcolor="#1f77b4"]
        start
        end
    node[shape="box" style="filled" fillcolor="#ff7f0e"]
        process
        
    subgraph cluster_process {
        label = "Major logic"
        process
    }
    
    start -> process
    process -> end
    
}

以上呈现为:

我有第二张图:

digraph details {
    label = "Process details"
    
    edge [fillcolor="#a6cee3" color="#1f78b4"]
    
    node[shape="ellipse" style="filled" fillcolor="#1f77b4"]
        start
        end
    node[shape="box" style="filled" fillcolor="#ff7f0e"]
        details
    
    subgraph cluster_details {
        label = "Details"
        details
    }
    
    start -> details
    details -> end
}

渲染到:

问题

当我将以上两个图表放入同一个名为 supporting.dot 的 DOT 文件中并运行 dot -Tpng -o supporting.png supporting.dot 命令时，终端打印出一些胡言乱语，输出图像文件不会包含两个图形，它只包含第一个。是否可以在单个 DOT 文件中使用多个图形？如果是这样，我错过了什么？

问题不清楚要完成什么，但也许以下是一个起点

digraph G{
subgraph unit_test {
    label="Unit test"
    
    edge [fillcolor="#a6cee3" color="#1f78b4"]

    node[shape="ellipse" style="filled" fillcolor="#1f77b4"]
        start
        end
    node[shape="box" style="filled" fillcolor="#ff7f0e"]
        process
        
    subgraph cluster_process {
        label = "Major logic"
        process
    }
    
    start -> process
    process -> end
    
}

subgraph details {
    label = "Process details"
    
    edge [fillcolor="#a6cee3" color="#1f78b4"]
    
    node[shape="ellipse" style="filled" fillcolor="#1f77b4"]
        start1 [label="start"]
        end1 [label="end"]
    node[shape="box" style="filled" fillcolor="#ff7f0e"]
        details
    
    subgraph cluster_details {
        label = "Details"
        details
    }
    
    start1 -> details
    details -> end1
}

}

注意第二个子图中的命名/标签。
