This tutorial discusses the details to create Visio diagram in Python. It encompasses the stepwise algorithm and a working sample code to automate Visio diagram creation in Python. Moreover, you can choose to write the output Visio file in VSDX, VSD, and several other supported file formats.

Steps to Create Visio Diagram in Python

1. Install the Aspose.Diagram API to create Visio VSD or VSDX files
2. Initialize an object of the Diagram class
3. Load the master using an input stencil
4. Insert a rectangle shape with the add_shape() method and set different preferences
5. Export the output Visio diagram by calling the save() method

These steps summarize how to create Visio in Python. The process commences by making an empty diagram and initiating the stencil with the master shapes. Then, insert a shape by mentioning the position coordinates, shape size, and the target page number to conclude the process of Diagram creation.

Code to Create Visio Diagram Programmatically in Python

The code snippet above is a basic version of drawing any process diagram in Visio in Python. Furthermore, it can be enhanced further to draw a variety of shapes as well as different connectors to draw simple to complex diagrams as per your requirements. Likewise, the generated output diagram can be rendered to image or document file formats as per your needs.

This precise guide includes the details to create Visio diagram programmatically in Python. Besides, if you need to convert VSD files then read the article on Convert VSD to VSDX in Python.
