        .SYNOPSIS
            Creates a PSHMTL Chart.
    
        .DESCRIPTION
            Will render a Graph in Javascript using Chart.JS
    
        .PARAMETER Type
    
        Specifies the type of chart to generate.
    
        .EXAMPLE
    
            This example creates 3 different doughnut charts.
            In the oposite of a bar or line chart, mixing different datasets on the same doughnut chart won't be as much value as with the other types of charts.
            It is recommended to create a doughnut chart per dataset.
