Hi - I am looking for way to visualize the flow of data through a chronological sequence of categorical axes. Specifically, I want to show the number of people (measure) as they move through various locations (dimensions) from a start point to a finish point. I was able to get basically what I want with the alluvial plot in R (image 1), and am wondering if it is possible to replicate this in Dundas? I have been trying to get this using a Sankey diagram but it will only show the data hierarchically, which causes repeating dimension attributes in the same node (image 2). If I try to use source-target node pairs then it seems to just randomly lay out the nodes ignoring the order (image 3). Any help would be appreciated, as would any suggestions for other visualization types that might work.
image 1 - the desired result achieved in R:

image 2: Dundas Sankey hierarchical layout with repeating attributes
image 3: Dundas Sankey source-target with (apparently) random layout (this is only showing the first 2 of the 4 dimensions)
