How can I compare two networks to each other?
It is often helpful to create a map based on multiple Target Nodes. The map for Google is interesting. The map for Powerset is interesting. But what more can be learned by looking at a combined map fo Google and Powerset together?

Searching for and mapping 2 or more nodes
Using any of the three search methods, you can always search for more than one company, investor, person, or school. On the results page you can select and highlight multiple nodes from the lists of matching results to map together as a combined network. If you know the names of the two (or more) nodes you would like to map together, it is as simple as entering their names separated by commas in a search field, like "Google, Powerset". After selecting the nodes from the results and mapping them, you can see a map of the combined networks of Google and Powerset which shows how the two networks are interconnected.

You can do this for any two nodes, and any connections between them are easily identified. If there are no connections, the two networks will appear side by side, but unconnected.

Adding extra nodes to an existing map
If you are already viewing a map, you can add any of the nodes in the map as target nodes, adding their entire networks and creating combined network maps. Click on any node in the map and the information for that node will appear in the Information Window. In the information for every node that appears in the Information Window there is a link that says "Add to map." By clicking on that link you can add that node to the current map. If that node is already added to the map, then the link will say "Remove from map," and in this way you can manipulate your maps, adding and removing nodes, looking for connections in your networks until you find what you were looking for, or something else just as interesting.

Adding a second or third (or more) node to a map as a target node allows you to expand the network you are looking at, and removing those target nodes contracts the map. Adding and removing nodes, and clicking from tab to tab and applying different filters or Controls Panel settings allows you to mine the data in the networks, discover new information, and represent it visually to help others understand as well.
