What toolkit exists for drawing/working a beautiful graph in a browser?

Question

JavaScript

It is necessary to display an interactive graph in the browser, with the ability to drag and drop nodes and save / load from a file. The graph is not very big. It would be great if the nodes could be made in different shapes, different colors. I know about d3.js about sigma.js. The server part is in Java. Can be used on the gephi server and drawn on the client with sigma. I know about this option.
But can someone tell me more good options, I would be very grateful? I will consider paid ones.
