Flowcharts

Create a flowchart

Declare a chart and render it to a string.

var flow = new Flowchart();
var output = flow.Render();

Setup a flowchart

• Add init directive to set theme
• Set a title with SetHeader
• Add a comment with AddComment
• Add nodes with Node
• Add links with Link

flow.AddDirective(new DirectiveInitialize(KnownThemes.Forest));
flow.SetHeader(new Header("This is a test"));
flow.Comment("No comment");

flow.AddNode("A", "Hard edge", Shape.Box)
    .AddNode("B", "Round edge", Shape.RoundedBox);

flow.Link(flow["A"], flow["B"], Edge.Arrow.WithLabel("Link text"));

var c = flow.Node("C", "Decision", Shape.Rhombus);

var d = flow.Node("D", "Result One", Shape.Trapezoid);

var e = flow.Node("E", "Result Two", Shape.Circle);

flow.Link(flow["B"], c, Edge.Arrow);
flow.Link(c, d, Edge.Arrow.WithLabel("Yes"));
flow.Link(c, e, Edge.Arrow.WithLabel("No"));

Subgraphs

flow.Subgraph("Outer", Identifier.Next("sg"), FlowDirection.TopBottom, 
    sub =>
	{
		sub.Node("Something", Shape.Stadium);

		var sg = sub.Subgraph("Inner", "in1");
		sg.Node("A", "Hard edge", Shape.Box);
	});

Theme and Styles

Define a style by name and assign it to a node by it's identifier.

flow.AddDirective(new DirectiveInitialize(KnownThemes.Forest));
// or
flow.SetTheme(KnownThemes.Forest);
// or
flow.SetTheme(new ThemeVariables() {
    // set theme variables
});

var cd = flow.GetClassDefinitions();

cd.GetOrCreate("neat", s
    => new ClassDef(s)
        .Style("fill", "#f96")
        .Style("stroke", "#333")
        .Style("stroke-width", "2px")
        .Assign("A")
    );
