Linkgraph macro error in Confluence

[soumyajit]

Recently Plant UML linkgraph macro stop working, It's showing "There is an issue with your DOT/GraphVIZ installation ". Could you please help me regarding this matter? 

2 weeks ago  we migrated our confluence application from windows to linux OS. I am not sure it's related to the OS.

Hello,

You need to read the installation documentation of the plugin.

It does rely on some dependencies (graphiz namely) that need to be installed on the OS, yes.

The PlantUML Confluence Plugin depends on the Graphviz package. Please ensure that you have installed the package on your Confluence system.

Note that this is not needed for the regular plantUML rendering, but for additional macro that the plugin provides (LinkGraph being one of them).
