Visio diagram builders

Diagram builders turn structured application data into consistently laid-out VSDX pages. They are available for flowcharts, block diagrams, architecture, networks, network topology, dependencies, swimlanes, org charts, sequences, timelines, and generic graphs.

Architecture diagram

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

VisioDocument.Create("architecture.vsdx")
    .ArchitectureDiagram("System Overview", diagram => diagram
        .Title()
        .Legend()
        .Theme(VisioStyleTheme.Technical())
        .Region("vnet", "Virtual Network", 1, 0, 3, 2)
        .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();

Network topology

VisioDocument.Create("network-topology.vsdx")
    .NetworkTopologyDiagram("Branch topology", topology => topology
        .Title()
        .Root("internet", "Internet", VisioNetworkNodeKind.Internet)
        .Firewall("firewall", "Firewall")
        .Switch("core", "Core Switch")
        .Server("app", "App Server")
        .Database("db", "Database")
        .Workstation("finance", "Finance PC")
        .Subnet("edge", "Edge", "internet", "firewall", "core")
        .Subnet("servers", "Server Zone", "app", "db")
        .Ethernet("internet", "firewall", "WAN")
        .Trunk("firewall", "core", "uplink")
        .Trunk("core", "app", "10Gb")
        .Ethernet("app", "db"))
    .Save();

Sequence diagram

VisioDocument.Create("sequence.vsdx")
    .SequenceDiagram("Checkout sequence", sequence => sequence
        .Title()
        .Theme(VisioStyleTheme.Fluent())
        .Actor("customer", "Customer")
        .Participant("web", "Web App")
        .Control("api", "Orders API")
        .Database("db", "Orders DB")
        .Call("customer", "web", "Checkout")
        .Call("web", "api", "POST /orders")
        .Async("api", "db", "Persist order")
        .Return("api", "web", "201 Created")
        .SelfMessage("web", "Render receipt"))
    .Save();

Validate the result

IReadOnlyList<string> issues =
    VisioValidator.Validate("architecture.vsdx");

if (issues.Count > 0) {
    throw new InvalidDataException(string.Join(Environment.NewLine, issues));
}
