Aspose.Diagram for Java is a feature-rich Java API for manipulating Visio diagrams programmatically without requiring Microsoft Visio. The API supports working with popular Visio formats including VSD, VSDX, VDX, VSDM, VSSM, and VSSX. Recently, we have leveraged the capabilities of Aspose.Diagram for Java and made it possible to implement MS Visio automation features in Node.js applications. These features let you create, manipulate, convert & process MS Visio diagrams within your Node.
