<#
    This is a simple example demonstrating how to create a 3-tier web application diagram using the PSgraph module, without using any object icons.

    [System.IO.FileInfo] $Path = '~\Desktop\',
    [array] $Format = @('png'),

<#
    Starting with PowerShell v3, modules are auto-imported when needed. Importing the module here ensures clarity and avoids ambiguity.

# Import-Module AsBuiltReport.Diagram -Force -Verbose:$false

<#
    Since the diagram output is a file, specify the output folder path using $OutputFolderPath.

$OutputFolderPath = Resolve-Path $Path

<#
    The $MainGraphLabel variable sets the main title of the diagram.

$MainGraphLabel = '3tier Web Application Diagram'

        This block creates a diagram with three servers, each represented by a custom node label and shape (without object icons).
    #>

    Node -Name 'Web-Server-01' -Attributes @{Label = 'Web-Server-01'; shape = 'rectangle'; fillColor = 'Green'; fontsize = 14 }
    Node -Name 'App-Server-01' -Attributes @{Label = 'App-Server-01'; shape = 'rectangle'; fillColor = 'Blue'; fontsize = 14 }
    Node -Name 'Db-Server-01' -Attributes @{Label = 'Db-Server-01'; shape = 'rectangle'; fillColor = 'Red'; fontsize = 14 }
}

<#
    The New-AbrDiagram cmdlet generates the diagram.
    -InputObject: Accepts the custom object defined above.
    -OutputFolderPath: Specifies where to save the generated diagram.
    -Format: Sets the output format (png, jpg, svg, etc.).
    -ImagesObj: Passes a hashtable of images for custom icons.
    -MainDiagramLabel: Sets the diagram's title.
    -Filename: Specifies the output file name (without extension).
    -LogoName: Selects an image from the hashtable to use as the diagram logo.
    -DraftMode: If set to $true, generates a draft version of the diagram for troubleshooting.
    If the specified logo image is not found, a default no_icon.png is used.
