# ** This time we will extend the edges size using the Graphviz minlen attribute. ** <# Simple example of how to create a 3 tier web application diagram using the Diagrammer module. Without using any object icons. #> [CmdletBinding()] param ( [System.IO.FileInfo] $Path = '~\Desktop\', [array] $Format = @('png'), [bool] $DraftMode = $false ) <# From Powershell v3 onwards, the module should not need to be explicitly imported. It is included here to avoid any ambiguity. #> Import-Module Diagrammer.Core -Force -Verbose:$false <# As the output of the diagram is a file, we need to specify the output folder path. In this example, $OutputFolderPath #> $OutputFolderPath = Resolve-Path $Path <# The $MainGraphLabel variable is used to set the main title of the diagram. #> $MainGraphLabel = 'Web Application Diagram' $example3 = & { <# This creates a 3 server diagram with custom node labels and shapes (No Object icons). The Node statements create the nodes in the diagram.

The Edge statements create connections between the nodes.

The -InputObject parameter accepts the custom object created above. The -OutputFolderPath parameter specifies where to save the generated diagram. The -Format parameter specifies the output format (png, jpg, svg, etc.). The -ImagesObj parameter passes the hashtable of images for custom icons. The -MainDiagramLabel parameter sets the title of the diagram. The -Filename parameter specifies the name of the output file (without extension). The -LogoName parameter specifies which image from the hashtable to use as a logo in the diagram. If the specified logo image is not found in the hashtable, the diagram will be generated using a no_icon.png [?]. The -Direction parameter sets the layout direction of the diagram. Options are: left-to-right, top-to-bottom. The layout is set to top-to-bottom (Top to Bottom) using the Graph attribute. The -DraftMode parameter, when set to $true, generates a draft version of the diagram for troubleshooting. #> New-Diagrammer -InputObject $example3 -OutputFolderPath $OutputFolderPath -Format $Format -MainDiagramLabel $MainGraphLabel -Filename Example3 -LogoName "Main_Logo" -Direction top-to-bottom -DraftMode:$DraftMode |
