Mine is just like the train viz provided at the link. My question is how would I create a dash-board that will allow me to select either a departure location or a destination location from a master map view and view a map with paths associated only with what was selected. The example shows only "Deliveries Out of Berlin". What if there were deliveries from Hamburg and Vienna as well? How could you drill down to only show those paths that originated from on of those locations?
In my scenario, I am mapping referral locations between one office and another. I have organized my data as shown in the example, but it gets far more complex as there are many originations and many destinations.
