Create node in graphviz using polygon as icon and text label-CodePudding

Is there any way to create a node in Graphviz that looks like the below? (Placing a hexagon and text side by side inside the node instead of just placing text inside box)

CodePudding user response：

You can't easily embed nodes within other nodes, but you can insert images into nodes. Create an image (or images) with the polygon shape(s) and insert them into an HTML-style node (record-style would probably also work).
Like so:

digraph i{
 {rank=same
  n1 [shape=plaintext,label=<
  <TABLE CELLSPACING="0" CELLPADDING="0" BORDER="1" cellborder="0"> 
  <TR><TD FIXEDSIZE="true" height="20" width="20"><IMG  SRC="cow.png" scale="true"/></TD><TD>some text</TD></TR>
  </TABLE>
  >
  ]

  n2 [shape=plaintext,label=<
  <TABLE CELLSPACING="0" CELLPADDING="0" BORDER="1" cellborder="0" >
  <TR><TD colspan="2" bgcolor="green1">Step</TD></TR>
  <TR><TD FIXEDSIZE="true" height="20" width="20"><IMG  SRC="cow.png" scale="true"/></TD><TD>some text</TD></TR>
  </TABLE>
  >
  ]
  n1 -> n2
  }
}
