Shields.GraphViz is a .NET wrapper for GraphViz. Easily enhance your applications with graph visualizations.

NuGet package ID: Shields.GraphViz

Example

First define a graph.

Graph graph = Graph.Undirected
    .Add(EdgeStatement.For("a", "b"))
    .Add(EdgeStatement.For("a", "c"));

Then render the graph to a stream.

IRenderer renderer = new Renderer(graphVizBin);
using (Stream file = File.Create("graph.png"))
{
    await renderer.RunAsync(
        graph, file,
        RendererLayouts.Dot,
        RendererFormats.Png,
        CancellationToken.None);
}

The location of your GraphViz installation, which is typically something like C:\Program Files\Graphviz\bin, should be supplied as the value of graphVizBin.

The output graph.png follows.

Features

• Fluent API for defining graphs
