Visio Diagrams

Edit on GitHub

Generate VSDX diagrams with builders, pages, shapes, connectors, stencils, and graph layouts.

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, timelines, sequences, swimlanes, or process diagrams produced from business system exports.
  • Native or external stencil-pack diagrams generated from installed Visio stencils or .vssx repositories.
  • Report pipelines that need a diagram artifact alongside Word, Excel, or PowerPoint output.

Building blocks

  • Documents and pages to organize one or more related views.
  • Shapes, masters, stencils, and catalogs for generated, native, and external-pack visuals.
  • Connectors for relationships, directional flows, labels, Shape Data, and hyperlinks.
  • Diagram builders for flowcharts, architecture, networks, dependencies, swimlanes, org charts, timelines, sequences, and generic graphs.
  • Quality and polish helpers for page fitting, text sizing, connector labels, and visual validation.

Quick start

using OfficeIMO.Visio;
using OfficeIMO.Visio.Diagrams;

VisioDocument.Create("topology.vsdx")
    .ArchitectureDiagram("System Overview", diagram => diagram
        .Title()
        .Legend()
        .Theme(VisioStyleTheme.Technical())
        .Actor("users", "Users", 0, 1)
        .Gateway("gateway", "Gateway", 1, 1)
        .Service("api", "API", 2, 1)
        .Database("database", "Database", 3, 1)
        .DataFlow("users", "gateway", "HTTPS")
        .ControlFlow("gateway", "api", "route")
        .DataFlow("api", "database", "SQL"))
    .Save();
  1. Define the nodes and relationships you want to visualize from your source data.
  2. Choose a domain builder, such as architecture, network, flowchart, dependency, swimlane, timeline, or graph.
  3. Use generated catalogs, installed Visio stencils, or external .vssx packs when real domain symbols matter.
  4. Attach Shape Data, hyperlinks, and stable IDs so regenerated diagrams remain searchable and diff-friendly.
  5. Save the .vsdx output as a build artifact or generated report attachment.
