I am newbie in ROS and Gazebo simulation.

Basically, I have a web (using web socket) which display the stream map image from robot. The webpage connects to the actual robot's ROS bridge which equipped with LIDAR to capture map.

I want to avoid using actual robot and LIDAR when testing the webpage functionality. I realize Gazebo did a simulation, however, I am not sure if I can use Gazebo to achieve the purpose.

please guide me.
