Naming the subgraph should be optional about psgraph HOT 1 CLOSED

This works. However, if one defines a attributes hashtable on the subgraph like SubGraph @{style='filled';color='lightgrey'} -ScriptBlock { ... }. Without using the -Attributes parameter PSGraph fails with

Error: <stdin>: syntax error in line 4 near '.'
Export-PSGraph : System error.
At /gitRepos/PowerShellTooling/Public/PowerShellInfo/Out-PSModuleCallGraph.ps1:473 char:22
+         $graphData | Export-PSGraph -ShowGraph

+ CategoryInfo          : NotSpecified: (:) [Write-Error], ParseException

I guess its okay, but could maybe be improved. I would think that this happens because of parameter location awareness. If one cannot avoid using -Attributes the error message could be improved I think.

Thank you very much.
