Aspose.Diagram FOSS
Create, edit, and convert Visio diagrams programmatically. Open-source, MIT licensed, with no Microsoft Visio required.
Aspose.Diagram FOSS is coming soon as a specialized open-source library for creating, editing, and converting Microsoft Visio files such as VSD, VSDX, and VDX, without needing Microsoft Visio. You will be able to work with shapes, connectors, layers, pages, styles, and layouts, making it a good choice for diagram visualization, business process modeling, network diagrams, org charts, and technical drawings. The library will let you load and read existing diagrams, add shapes and links, apply layout algorithms, and export diagrams to PDF, HTML, SVG, or images. It is designed for complete control over Visio content and will work fully offline and across different platforms, making it ideal for adding Visio file support to enterprise apps, cloud tools, or automation workflows.
