+If you want to write accessors that traverse a path in an object to get properties, do this:
+
+    thingElements.text(accessor({ path: 'data/meta/label'));
+
+That will make it look for an object named `data`, then look for an object named `meta` in that, then look for a property named `label` within that. If you need to traverse arrays you can use array indexes in the path, e.g. `data/list/3/label`.
