Overview of the OfficeIMO.Visio package for generating VSDX diagrams with pages, shapes, and connectors.

Visio Diagrams

OfficeIMO.Visio focuses on generating .vsdx diagrams from pure .NET code. It is a good fit when your application already knows the topology, flow, or system shape it wants to draw and you need a repeatable way to emit diagrams without manual Visio authoring.

Good use cases

  • Infrastructure and architecture diagrams generated from configuration or inventory data.
  • Network maps, dependency graphs, and deployment flows.
  • Org charts or process diagrams produced from business system exports.
  • Report pipelines that need a diagram artifact alongside Word, Excel, or PowerPoint output.

Building blocks

  • Diagrams and pages to organize one or more related views.
  • Shapes with text, size, fill color, and placement.
  • Connectors for relationships and directional flows between shapes.
  • Measurement helpers so positioning can stay readable in code.

Quick start

using OfficeIMO.Visio;

using var diagram = VisioDiagram.Create("topology.vsdx");
var page = diagram.AddPage("System Overview");

var frontend = page.AddShape("Frontend", 2.0, 8.0);
var api = page.AddShape("API", 5.0, 8.0);
var database = page.AddShape("Database", 8.0, 8.0);

page.AddConnector(frontend, api, "HTTPS");
page.AddConnector(api, database, "SQL");

diagram.Save();
  1. Define the nodes you want to visualize from your source data.
  2. Map each node to a stable shape position and visual style.
  3. Add connectors that represent traffic, dependency, or process flow.
  4. Save the .vsdx output as a build artifact or generated report attachment.
