尝试画了个RNN的图，效果如下：
RNN结构图
代码如下：
digraph ""
{
color=white;
labelloc = "b";
#node[color="#FF6347"]
edge[penwidth="1"]
node [shape=plaintext];
n001 [label="Input Layer"];
n002 [label="Hidden Layer"];
n004 [label="Output Layer"];
n001 -> n002;
n002 -> n004;
node [shape=record, label=" | | | | | ...| ",height=".3",penwidth=".8"];
n01 [label="x(t-1)", fillcolor="#CCE5FF", style=filled] ;
n02 [label="x(t)", fillcolor="#CCE5FF", style=filled] ;
node [shape=Mrecord, label=" | | | | | ...| ",height=".3"];
n03 [label="...", fillcolor="#FFE6CC", style=filled] ;
n04 [label="h(t-1)", fillcolor="#FFE6CC", style=filled] ;
n05 [label="h(t)", fillcolor="#FFE6CC", style=filled] ;
n08 [label="...", fillcolor="#FFE6CC", style=filled] ;
node [shape=record, label=" | | | | | ...| ",height=".3"];
n06 [label="o(t-1)", fillcolor="#CCE5FF", style=filled] ;
n07 [label="o(t)", fillcolor="#CCE5FF", style=filled] ;
n01 -> n04 [label="U"] ;
n03 -> n04 [label="W"] ;
n02 -> n05 [label="U"];
n04 -> n05 [label="W"];
n04 -> n06 [label="V"];
n05 -> n07 [label="V"];
n05 -> n08 [label="W"];
{rank=same; n001 n01 n02}
{rank=same; n002 n03 n04 n05 n08}
{rank=same; n004 n06 n07}
}
