Research direction

First, examine how lasso selection is implemented for the canvas (likely in the canvas module). Then identify the corresponding code for the node graph and replicate the behavior, ensuring consistency in Ctrl+drag interaction. Look at the selection event handling and shape representation to adapt to node structure.
