Any clue how to let user create graphitem live with mouse clicks ?

[Michał Piech]

Hello

First of all thanks for pyqtgraph, it's been really helpful.

I am trying to run a simulation on user defined graph so I wanted to let user create GraphItem.

Best way would be through mouse interactions - left click creates a node, drag between nodes creates a vertex,

right click on a vertex opens up a context menu for choosing vertex-cost.

Second way would be creating a graph with buttons/slidelists.

The problem is that I need to create and update the graph live.

Any idea how to do it ?
