Do you have something like this?

Can I do something like this in GOJS?

My customer wants this SmileUnhappy is probably the most similar, except that you want to show only one level of children, and you want to support expanding in place rather than recentering.

So that example looks easy enough to implement in GoJS, once you have learned how to program GoJS.

We work in GOJS for more than 8 months now with various layouts available here including this, but nothing excited me and my client. However the D3JS samples does it. :-) anyway, thanks.
