Overview

NOV Diagram for .NET is part of the Nevron Open Vision (NOV) suite, offering a fully managed, extensible, and powerful diagramming framework for Blazor WebAssembly, WPF, WinForms, and macOS. It enables developers to embed Microsoft‑Visio‑like diagramming capabilities—including flowcharts, org charts, network maps and more—into .NET applications using a single code base. Built on the NOV Document Object Model, it delivers consistent, high-performance vector graphics that integrate with other NOV controls like charts and rich text.

Features and Capabilities

• **Extensible Diagramming Architecture: **NOV Diagram is built on a scalable, .NET‑standard Document Object Model and offers clean, logical APIs for shapes, documents, pages, and libraries.
• **Platform‑Independent Cross‑Platform UI: **Works across Blazor WebAssembly, Windows (WinForms, WPF), and Mac from a single code base, thanks to NOV’s host abstraction layer.
• **Predefined Shape Libraries & Visio Integration: **Includes numerous built‑in shapes for various diagram types and supports reuse of libraries from MyDraw or Microsoft Visio.
• **Automatic Layout Engine: **Advanced graph and tree automatic layouts let you organize large or data-driven diagrams automatically.
• **MVC‑Style Model‑View‑Controller Architecture: **Separation between model (NDocument), multiple views, and interaction tools enables flexible GUI design and MVC integration.
• **Rich Interactivity & Preview Tools: **Provides drag‑drop, zoom/pan, previews for move/resize operations, undo/redo, and customizable tool controllers per view.
• **Seamless Integration with Other NOV Controls: **You can embed NOV charts, rich text, grids, gauges, or barcodes directly into diagrams and vice versa.
• **High‑Quality Rendering & Export: **Vector-based rendering with GPU acceleration where available, perfect for hi‑DPI or 4K displays; supports export to PNG, SVG, PDF, EMF, and more.
• **Rich Development Resources: **Offers hundreds of example applications with source code to accelerate developer onboarding across platforms.
