Complex heirarchical tree layout

I need to create an hierarchical tree (something like this), but i need some features: - Ability to design the nodes as i like (size, background image, fonts etc.) - Automatic layout - Ability to connect nodes by drag N' drop I've looked at GoJs and its great, but it's canvas based, and i couldn't find a way to make the nodes look exactly as I want (actually not even remotely close). I've also looked at d3.js which is also great but again, since it's SVG it's haard to design the nodes. The main hustle here is the layout, and connecting the nodes, i can handle the Drag N' Drop my self, Is there a library out there that can handle the layout for me , so i can create the required div's, design them as i see fit and let the library do just the layout stuff?
