-obographs-python command line:
+This library is integrated into [Ontology Access Kit (OAK)](https://github.com/INCATools/ontology-access-kit) to support its [`viz` subcommand](https://incatools.github.io/ontology-access-kit/cli.html#runoak-viz). For example:
 
 ```bash
-ogr -p subClassOf BFO:0000050 -r go -t png   a nucleus
+runoak -i ontobee: viz HP:0000787
 ```
 
 This proceeds by:
 
- 1. Using the python obographs library to extract a networkx subgraph around the specified node
+ 1. Using the [python oaklib library](https://incatools.github.io/ontology-access-kit/intro/tutorial02.html) to extract a subgraph around the specified node
  2. Write as obographs-json
