The FlowMap object contains the properties of a Flow Map. Flow maps are created with the CreateFlowMap method of the PlotDocument object.
Derived from: Map object (All methods and properties of Map apply to this object.)

Example
This example creates a flow map that connects the boundary centroids with flow lines.
Sub Main
'Declares mvApp as an object
Dim mvapp As Object
'Creates an instance of the MapViewer Application
'object and assigns it to the variable named "mvapp"
Set mvapp = CreateObject("MapViewer.Application")
'Make MapViewer visible
mvapp.Visible = True
'Declare Plot as Object
Dim Plot As Object
'Creates a new map window
Set Plot = mvapp.Documents.Add(mvDocPlot)
'Declare FlowMap as object
Dim FlowMap As Object
'Create a flow map using the connect centroids method
Set FlowMap = Plot.CreateFlowMap(BoundaryFileName:=mvapp.ApplicationFolder + _
"\Samples\us50ll.gsb", DataFileName:= mvapp.ApplicationFolder + _
"\ Samples\flow.dat", FlowMethod:= mvFlowConnectEnds, PIDCol:=1, _
