I am experimenting with the sample report for the Network Navigation Chart from the Office Store and think that the Network Navigation Chart interactions may contain a bug. (I've found the same thing in my personal workbooks)
When I click on a node in the network chart the other tables respond and filter accordingly. If I click that node again, or deselect it in some other way, the other tables stay filtered. There seems to be no way to unfilter the tables once a node selection has been made in this way.
Can you please help solve this issue or let me know the answer? It would be great if the filtering in this visualisation worked in the same way as the other Power BI charts.
