In this tutorial: http://wiki.ros.org/stdr_simulator/Tu... in section 4 it says:

After you have subscribed to the correct topic, you should see the generated map by gmapping...

What's the "correct topic" and how do I subscribe to it in Rviz? Thanks!

You can get the correct topic in RViz by

Clicking the "Add" button
Clicking on the "By topic" tab in the popup
Search for the topic under the /gmapping node (or whatever name you have given it) that has a message type of nav_msgs/OccupancyGrid (most likely the /map topic)
Click "Ok"
