.. inspection/index: Visualization Tools ################### nGraph provides serialization and deserialization facilities along with the ability to create image formats. When visualization is enabled, a ``dot`` file is generated, along with a ``png``. The default can be adjusted by setting the ``NGRAPH_VISUALIZE_TREE_OUTPUT_FORMAT`` flag to another format, like PDF. Note: Large graphs are usually not legible with formats like PDF. Large graphs may require additional work to get into a human-readable format. We have provided a script to convert the `most common default output`_, nGraph JSON, to an output that is better able to handle detailed graphs; however, we do not offer user support for this script. After running the script, you should have a ``.graphml`` that can be imported and inspected with third-party tools like: #. `Gephi`_ #. `Cytoscape`_ .. #. `Netron`_ support tentatively planned to come soon .. _CMakeLists.txt: https://github.com/NervanaSystems/ngraph/blob/master/CMakeLists.txt .. _most common default output: https://github.com/NervanaSystems/ngraph/contrib/tools/graphml/ngraph_json_to_graphml.py .. _Netron: https://github.com/lutzroeder/netron/blob/master/README.md .. _Gephi: https://gephi.org .. _Cytoscape: https://cytoscape.org
