Just posted this on issue #12 which looks the same as this issue -

OK I think I've resolved this. Seems to be an error with the install-graphviz not installing graphviz into the right location. A workaround is to use the chocolatey version of graphviz, but that wasn't working either, because my machine(s) were using TLS1.3 to try and download chocolatey.

To resolve the TLS1.3 error (if you get it) - Powershell AS ADMIN:

New-Item 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' -Force | Out-Null

New-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' -name 'Enabled' -value '0' -PropertyType 'DWord' -Force | Out-Null

New-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Server' -name 'DisabledByDefault' -value 1 -PropertyType 'DWord' -Force | Out-Null

New-Item 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client' -Force | Out-Null

New-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client' -name 'Enabled' -value '0' -PropertyType 'DWord' -Force | Out-Null

New-ItemProperty -path 'HKLM:\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client' -name 'DisabledByDefault' -value 1 -PropertyType 'DWord' -Force | Out-Null

Then change your .NET Framework default TLS version -powershell AS ADMIN:

reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:64 reg add HKLM\SOFTWARE\Microsoft\.NETFramework\v4.0.30319 /v SystemDefaultTlsVersions /t REG_DWORD /d 1 /f /reg:32

Install chocolatey - powershell AS ADMIN:

iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))

Close and reopen powershell, then Install graphviz via chocolatey - powershell AS ADMIN:

choco install graphviz

You should then be able to run AzViz in a NON-ADMIN powershell session as per the instructions

Depending on how your executionpolicy is set (and whether or not you can change it) you might still be unable to run/ might need to run azviz as admin

I had to output the file instead of using showvisualization for it to work when running as admin - get-azviz -resourcegroup demo2 -theme light -verbose -outputformat png -OutputFilePath C:\Output\azure.png

Removed this installation piece from the module and marked it as a prerequisite in the documentation. closing this issue now.
