Graph Explorer is an open source .NET control which will help you navigate and explore Directed Acyclic Graphs (DAG).

A sample project is included to demonstrate the use of the control.

The component relies on GraphX for .NET an advanced graph visualization library as well as Orc.FilterBuilder, a visual control for building complex filtering options.

The component allows you visualize DAGs contained in a csv file or build diagrams of edges/nodes with unlimited levels of hierarchy.

The main features of the component are:

• Unlimited levels of hierarchy
• Loading data from csv files
• Saving and Loading of application state
• Exporting current application view as image
• View zoom in/out and panning
• Dragging, modifying and deleting of nodes and edges
• Highlights the selected node location as well as its owner.
• Double click on a node to open open a new window
• Delete, add and reorder of hierarchy relations
• Complex filtering nodes options

One of the main features of the control is the complex node filtering capability. It can filter the node visibility by selecting multiple parameters.

The control provides a simple process for saving and loading the current layout. The state is saved in a common .xml file.

Dragging of nodes is enabled after pressing the hand button.

User can modify or add more fields to any node by enabling the edit button.

By double clicking on a node a new tab is created with all neighboring nodes(immediate precedent and descendants).

##Create new chart

To display information contained in a csv file, press on the cog button:

Locate the data files on the settings window:

The Properties.cvs and Relationships.csv are two data files responsible for chart presentation.

The Properties.cvs file consist of three fields ID,Propert and Value and defines each nodes data.

The Relationships.csv file defines the relationship between each nodes, and only has two fields From and To. These columns will contain the ID for the node

NOTE: Collaboration is most welcome.
