Nevron Diagram for .NET features:

• Advanced automatic graph and tree layouts
• Numerous interactivity and editing features
• Hundreds of predefined shapes and extensibility options
• Tree/Graph Data Importers ... And much more...

Diagram Document Object Model
The Diagram Document Object Model represents the set of elements, which you can use to build a diagramming document. The Diagram Document Object Model is built on top of the Nevron DOM and in the context of the Nevron Diagram .NET product is simply called DOM. Following is a brief summary of the most important DOM elements and features:

• Elements-Diagrams are constructed by elements, which reside in a hierarchy, the root of which is a diagramming document.
• Documents-Documents are the root elements in the element hierarchies. They provide core support for services, view management and data exchange capabilities.
• Styling-The visual appearance of all diagram elements is controlled via styles. Styles can be locally specified (per each element individually) or reused via inheritance or style sheets.
• Shapes and Groups-When constructing diagrams, you basically work with shapes. Nevron Diagram for .NET provides an extensive set of predefined shapes
• Data Structures- Nevron Diagram for .NET has a built-in support for graph and tree data structures and the core operations with them.
• Routing-Nevron Diagram for .NET has built-in support for automatic obstacle avoidance routing.
• Bridges-Bridges (hops) are a special type of decoration, which is displayed on connectors self-intersections or intersections with other connectors below it in the Z order.
• Print Manager-Drawings can be printed on single or multiple pages. Implemented is built in support for print preview and page setup.
• Raster Image Export-Drawings can be exported to an image of any type (JPG, PNG, BMP etc.).
• Vector Image Export-Drawings can be exported to Pdf, Flash, SVG, Silverlight (XAML) and EMF vector formats.
• Undo and Redo-The entire DOM is protected by history. The history is implemented as a service so you can easily override it, stop or pause it.
• Batches-Batches serve as a functionality layer between documents and views. Batches are designed to operate with multiple elements and record a single history transaction.
• Event Handling-All events are fired from an event sink service, which provides you with the ability to consistently intercept all types of events regardless of the diagram you work with. Interactivity events (mouse, keyboard and drag drop events) support event bubbling.

Automatic Layouts
The automatic arrangement of diagrams is an indispensable feature, especially when diagrams are either too large or are automatically generated. Nevron Diagram for .NET comes equipped with a sophisticated set of automatic layouts. Following is a brief overview:

• Force Directed Layouts-Implemented are barycenter, spring and symmetrical layouts. They are suitable for any kind of graph and produce straight line graph drawings.
• Layered Graph Layout-Layouts a graph in layers. It produces polyline graph drawings and is very appropriate for hierarchically organized graphs.
• Orthogonal Graph Layout-Draws a graph only with horizontal and vertical line segments. It is suitable for any kind of graph and addresses issues like crossing, bend and area minimization.
• Radial Graph Layout-Draws a graph in radial circles. It is suitable for any kind of graph and produces straight line graph drawings.
• Layered Tree Layout-Layouts a tree in layers. Produces straight line and orthogonal tree drawings.
• Compact Depth Tree Layout-Layouts a tree with minimal depth. Produces straight line and orthogonal tree drawings.
• Tip Over Tree Layout-Layouts a tree by placing children in either a row or a col. Produces orthogonal tree drawings.
• Balloon Tree Layout-Layouts a tree by placing the children in circles around their parents. Produces straight line tree drawings.
• Stack Layout-Stacks the cells in horizontal or vertical order.
• Flow Layout-Arranges the cells in horizontal or vertical lanes.
• Dock Layout-A space eating cells layout, which places vertices at per-vertex specified docking areas of the currently available layout area.
• Table Layout-Arranges the cells in a tabular manner.

Predefined Shapes
Nevron Diagram for .NET comes equipped with numerous predefined shapes, which can come handy in many applications. The predefined shapes are consistently created by shape factories. Currently implemented are shape factories, which create shapes from the following categories:

Maps (part of Nevron Diagram for .NET Enterprise edition)
Nevron Diagram for .NET has built-in support for display of maps. ESRI shapefiles (the industry leading standard for storing map data) can be easily imported in any diagram with just a few lines of code.Following is a brief overview of the most important mapping features:

• Support for the ESRI shapefile format - the industry leading standard
• Support for 22 projection types
• Intelligent layer properties show/hide layers based on zoom level
• Automatic naming and labeling of map elements through data field association
• Full programmatic access to map elements including shapes and paths

Thick client (WinForm) and Visual Editing
Nevron Diagram for .NET provides built-in support for developing thick client diagramming applications. It comes equipped with several ready to use controls, which can help you to create a standalone diagramming application in minutes. In fact, the Diagram Designer application, which is included in the package, is built by only assembling the following controls:

• Drawing View-The drawing view helps you to display and edit drawing documents.
• Library View-The library view helps you to display and edit library documents. You can drag and drop shapes from the library view to the drawing view and vice versa.
• Pan and Zoom Control-The pan and zoom control helps you to display a bird's eye view of the document, which is being edited in its master drawing view. It also lets you interactively pan and zoom the master drawing view.
• Diagram Command Bars Manager-The diagram command bars manager helps you to visualize and execute the set of predefined commands, which can be performed on drawing and library views.
• Diagram Properties Browser-The diagram, properties browser helps you to instantly edit the properties of the document, the active layer, the selected element or the view.
• Diagram Status Bar-The diagram status bar displays important information about the current state of a drawing view (size of the selected element, keyboard state, measurement unit etc.)

Thin Client (ASP.NET) and AJAX
Nevron Diagram for .NET provides built-in support for developing interactive thin client diagramming applications. It can operate either in Postback Mode or in AJAX mode.

ASP.NET AJAX Mode
Nevron Diagram for .NET comes with a powerful, yet easy to use built-in set of AJAX interactivity styles. It is based on the Nevron AJAX Framework, which is a reliable, fault tolerant and cross-browser compatible JavaScript library, that converts the simple diagram images inside your web page into an interactive client side application with flicker-free asynchronous image updates.

ASP.NET Postback Mode
Nevron Diagram for .NET provides a set of useful features that help you to add interactivity to your web application, while sticking to the more traditional and simple postback technology:

Interactive Image Maps
Nevron Diagram for .NET can send an HTML image map to the client browser, which allows you to build web applications with drill down capabilities.

SVG Image Response
The SVG image response sends to the client a rich vector graphics image. This helps you to have the diagram image rescaled in the web browser without loss of quality, which would be the case if rescaling raster format images. The SVG format also allows for client side interactivity like mouse hover effects.
