Intern:Editorial/NetworkGraph/Terms

With the network graph of terms, you can explore the terminologies in PANGAEA. It shows terms as nodes. Relations between terms are displayed as aop leftrrows. Different colors indicate diffent types of terms and relations.

Get started

 * 1) Open a term in the detail form.
 * 2) Click the "Network Graph" button in the header of the form.

Now you get a tab with the initial network of your term. It shows your term in the center with all its related terms around.

From here, you can explore the neighbourhood of your term and discover the structure of your terminologies.

Components in the Network Graph Tab
The view in the tab is composed of several components to help you navigate and view your terms.

Network View
This is the center view that displays terms as nodes and relationships between terms as arrows.

Toolbar
At the top left, there is the toolbar. There you can switch the interaction mode, e.g. move tool, select tool, expand / collapse nodes and the fisheye.

Minimap
The minimap at the left bottom shows as overview of the whole network. Use it in big graphs to see where you are and quickly move around the space.

Node Legend
At the top right, the node colour code is shown. If you have terms from different terminologies in your graph, the nodes will have different colours that are explained in this legend.

Nodes
Nodes are terms, yes. The name is witten on it.

A node can have two states:


 * Expanded: The colour corresponds to the related terminology (random, but persistent). It has all related terms shown with the corresponding relations. The outline color corresponds to the term category.
 * Collapsed: Grey color. These nodes do not show all their relations, only to those nodes that are within the graph.

General Interaction with the Graph
There are general things you can do with the graph that work in most modes (you change the mode by using the toolbar).

Click to Select Node
Click on a node and it will be selected / deselected. Sometimes, it hepls to click on free space to deselect everything. Selectig a node also fades out all unrelated nodes in the graph, so you can see its direct neighbours clearly.

Hold shift key to extend / reduce selection.

Puts the tag(s) of selected nodes next to the toolbar.
