-### Resource generation
+### Custom Visualization
+
+If you want to add a custom visualization to a dataset, you can do this:
+
+        dataset.set_custom_viz(URL)
+
+URL is a string containing the url of your visualization.
+
+You can get any existing visualization like this:
+
+        url = dataset.get_custom_viz()
+
+The return value is a string if a visualization has been set on the dataset,
+otherwise it is None.
+
+### Resource Generation
 
 There are a range of helpful functions to generate resources. In the following
 examples, RESOURCE DATA takes the form {"name": NAME, "description":
