Label vs Tooltip and how to modify

[Calantha21]

Hi Chris,

I have the same dataset as before
Parent Child Parent ID Child ID
null Company 1 null 1
Company 1 Company 2 1 2
Company 1 Company 3 1 3
Company 1 Company 4 1 4

etc.

When we mouse over a node, we get 1:2:NaN in the tooltip because we are using the IDs to link.
I tried to set label to "Child" but that doesn't seem to change anything on the chart. We'd like the tooltip to show just the name of the entity when we mouse over it (e.g., child) but I don't see anywhere to modify the tooltip - do we have to do that in the code?

Thanks,
