 <h3>Visualize a Graph Model</h3>
 <p>
 The graph model is defined by following rules:
 <ul>
 <li>A node could have a set of ports.
 <li>A port has a single node assigned.
 <li>A link could have a source and a target port assigned.
 </ul>

 <h3>Drag&amp;Drop Style of Work</h3>
 <p>
 Most of the actions are possible to invoke using left mouse button: selection (single and rectangular), moving objects, creating links, relinking.
 Shift key modifier is used for invert selection. Ctrl key is used to entering Alternate mode.

 <h3>Visual Feedback</h3>
 <ul>
 <li>Objects selection.
 <li>Objects highlighting - allows second type of visual feedback e.g. highlighing all links that are attached to selected nodes.
 <li>Mouse over effect on all active objects.
 </ul>

 <h3>Looks and Feels</h3>
 <p>
 API allows to plug in L&amp;F of all objects. Each object could have different L&amp;F.

 <h3>Extensible</h3>
 <p>
 The library defines interfaces that could implemented by 3rd-party and plugged in the library. Following interfaces are in the API:
 <ul>
 <li>Document Model - holds document data.
 <li>Node Model - holds node data.
 <li>Link Model - holds link data.
 <li>Port Model - holds port data.
 <li>Document Renderer - defines look of a background.
 <li>Node Renderer - defines look of a node.
 <li>Link Renderer - defines look of a link.
 <li>Port Renderer - defines look of a port.
 <li>Nodes Layouter - resolves nodes positions and support of animated node positioning.
 <li>View Controller - defines user behaviour e.g. left-clicking on a node means that the particular node should be selected by model
 <li>Model Event Handler - receives events from the library and view controller and makes changes in the model which are propagated back to the graph library and visualized e.g. an event that a new link should be created.
 </ul>

 <h3>Multi View</h3>
 <p>
 Two possible multi-views:
 <ul>
 <li>View Cloning - two JComponents which are showing exactly the same  content including looks and feels.
 <li>Views of Model - two JComponents which are showning the same model but could use different looks and feels.
 </ul>

 <h3>Multi Layers</h3>
 <p>
 Rendering of objects is done in layers. Each object could be rendered in more than one layer e.g. a link should be renderer below nodes but when the link is selected it should be renderer over nodes, ...

 <h3>Undo-Redo</h3>
 <p>
 Allows undo/redo actions on a view e.g. node position changes.

 <h3>Zoom in/out</h3>
 <p>
 A view allows to zoom in and out using a zoom factor property.

 <h3>In-place Editing</h3>
 <p>
 A renderer could specify in-place editor e.g. when you double-click on a text, an in-place editor is shown in the scene and allows you to edit it.

 <h3>Snap-to-grid</h3>
 <p>
 A node is snapped to a grid when it moves.

 <h3>Alternative Node</h3>
 <p>
 Special (second) editing mode dedicated for modifing link (using their control points) and ports locations. By default editing mode is invoked by pressing Ctrl key.

 <h3>Orthogonal Link Router</h3>
 <p>
 A link router which creates orthogonal path that keep away from other objects on the scene.

 <h3>Breadth-first Nodes Layouter</h3>
 <p>
 A nodes layouter which layouts nodes using breadth-first algorithm.
