Graphviz is open source graph visualization software. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. Visit for more information.

Graphviz can be used in Sympathy for Data to visualize profiling call graphs and decisiontrees for machinlearning models. To start using Graphviz, it must be installed and then configured. This is completely optional and necessary only to enable these visualizations.

Installing Graphviz

To obtain a copy of Graphviz, visit: Install it and note the install folder, which will be needed when Configuring Graphviz.

Configuring Graphviz

For the call graph file to be generated Graphviz will have to be installed and the path to the bin folder which contains dot will have to be in either PATH or Graphviz install path, see Debug Preferences.
