Any idea how to run rviz in a 2D mode?

edit

As long as many of us are trying install ROS on an embedded system and most of them do not have graphic cards. It is true that we could running rviz on another laptop to view the topics and debug, but when I want to package the robot as a product, we hope all the things are well self-included.

Seems it is possible to run rviz in Jetson TK1. But in my application, I hope to show 2D map and navigation paths and goals in rviz, running on Rasp Pi2(save cost). So I do not need the 3D stuff. I would like to seek ideas and suggestions that how I can configure rviz or maybe rewrite an small application for display information for 2D navigation, on an ARM board.

Or may be ROS will officially publish a 2D version rviz for all the embedded platform?

I would like to participate if anyone want to open a new project on github for this.
