    .SYNOPSIS
        Diagram the configuration of Veeam Backup & Replication infrastructure in PDF/SVG/DOT/PNG formats using PSGraph and Graphviz.
    .DESCRIPTION
        Diagram the configuration of Veeam Backup & Replication infrastructure in PDF/SVG/DOT/PNG formats using PSGraph and Graphviz.
    .PARAMETER Format
        Specifies the output format of the diagram.
        The supported output formats are PDF, PNG, DOT & SVG.
        Multiple output formats may be specified, separated by a comma.
    .PARAMETER NodeSeparation
        Controls Node separation ratio in visualization
        By default, NodeSeparation will be set to .60.
    .PARAMETER SectionSeparation
        Controls Section (Subgraph) separation ratio in visualization
        By default, NodeSeparation will be set to .75.
    .PARAMETER EdgeType
        Controls how edges lines appear in visualization
        The supported edge type are:
            'polyline', 'curved', 'ortho', 'line', 'spline'
        By default, EdgeType will be set to spline.
        References: https://graphviz.org/docs/attrs/splines/
    .PARAMETER OutputFolderPath
        Specifies the folder path to save the diagram.
    .PARAMETER Filename
        Specifies a filename for the diagram.
    .PARAMETER EnableEdgeDebug
        Control to enable edge debugging ( Dummy Edge and Node lines ).
    .PARAMETER EnableSubGraphDebug
        Control to enable subgraph debugging ( Subgraph Lines ).
    .PARAMETER EnableErrorDebug
        Control to enable error debugging.
    .PARAMETER AuthorName
        Allow to set footer signature Author Name.
    .PARAMETER CompanyName
        Allow to set footer signature Company Name.
    .PARAMETER Logo
        Allow to change the Veeam logo to a custom one.
        Image should be 400px x 100px or less in size.
    .PARAMETER SignatureLogo
        Allow to change the Diagrammer signature logo to a custom one.
        Image should be 120px x 130px or less in size.
    .PARAMETER Signature
        Allow the creation of footer signature.
        AuthorName and CompanyName must be set to use this property.
