I was playing around with the network nodes, using several workflows on the hub. I was interested to incorporate a network into a component.
Since all of the workflows from the Knime Challenge 35 used the Network Viewer (local), that’s the first one I tested. I found that it cant be incorporated into the view of a component like … say… a Table View does. I then tried all the image nodes which are recommended by the Workflow Coach. It seemed that the images produced when viewed as a component were truncated (not the whole screen was shown) as shown here:
One thing changed the course of my discovery:
I went on to play with the Network Viewer (not the Local version).
To my surprise, it can be viewed as a component! And it’s also interactive!
Hope this helps those in the future who’ll be looking for the same thing 
considering there are two versions of the node available out there. Choose the right one for your purpose.
