This workflow describes the network creation process and specifically creates the drug-drug co-occurence network. Here, we use the Network Creator node to create an empty network that can be filled with new nodes and edges by using the Object Inserter. Afterwards, we predict the ATC codes and create visual properties (color & shape) for the nodes within the network. These properties can be added by using the Feature Inserter node. After doing so, we use the Network Viewer JS (hidden in the View component) to visualize the network.
