GraphvizWpf

A WPF control that renders the Graphviz graphs described in the Dot language.
The control allows the creation of interactive graphs by adding mouse-click events, tooltips, and more.

Limitations

• Only dashed, dotted and solid line styles are supported.
• Specifying an image in a dot file like vertexName [image="imageName.png"] is not supported

How to use

• Copy the Graphviz dlls to the folder with the executable. This can be done by adding a prebuild event to your csproj file:

<Target Name="DownloadGraphviz" BeforeTargets="BeforeBuild" Condition="!Exists('$(BuildFolder)/Graphviz.zip')">
  <DownloadFile SourceUrl="https://gitlab.com/api/v4/projects/4207231/packages/generic/graphviz-releases/11.0.0/windows_10_cmake_Release_Graphviz-11.0.0-win64.zip" DestinationFolder="$(BuildFolder)" DestinationFileName="Graphviz.zip" />
  <Unzip SourceFiles="$(BuildFolder)Graphviz.zip" DestinationFolder="$(BuildFolder)" />
</Target>
<Target Name="CopyGraphvizBinariesToOutputFolder" AfterTargets="DownloadGraphviz" BeforeTargets="BeforeBuild" Condition="!Exists('$(OutputPath)/config6')">
  <ItemGroup>
    <GraphVizBinaries Include="$(BuildFolder)/Graphviz-*-win64/bin/*.dll;$(BuildFolder)/Graphviz-*-win64/bin/config6" />
  </ItemGroup>
  <Copy SourceFiles="@(GraphVizBinaries)" DestinationFolder="$(OutputPath)" />
</Target>

• Look at the example project Test from this repository, which shows how to make an interactive zoomable graph.

How the library works

The GraphvizWpf library uses Graphviz to convert the Dot graph representation to the Json format with the Dot drawing commands. Then these commands are executed by creating shapes on a WPF Canvas
