After installin Graphviz 7.1.0 exe on my windows system. I ran these commands  
echo ‘digraph { a-\> b }’ | dot -Tsvg \> output.svg  
explorer file:///C:/Temp/output.svg

I am getting the error as  
“This XML file does not appear to have any style information associated with it. The document tree is shown below.”

The command `echo 'digraph { a-> b }'` is a Linux OS command and does not work on Windows. OK, it works, but it does not do anything useful.  
And because **dot** received no useful input, it created no useful output.

Try this:

- use a text editor like notepad, emacs, vim, (not **word**!) and create a file that looks like this:

```auto
digraph X { 
  a->b->c
}

```

- save it in some findable directory
- name it something like myFirst.gv
- using the cmd window (or powershell) type  
`dot -Tsvg myFirst.gv >myFirst.svg`

Should work!
