Hey! I really liked using this tool as a very simple visualization for models, but there might be a bug in the FCNN style. Adding a extra node at the end of the model leads to a missing Output Layer label. Similarly, adding an extra node after that one leads to both nodes missing their labels.  I would have loved to try to PR and solve it myself, but I'm not too comfortable with JS, so I think I'm out of my league a little here!
