Hi I want to run slam as robot but I don't have any robot now. I just only have lidar sensor. So I want to make a virtual map and run slam in a virtual map by moving virtual robot like this.

And I want to visualize point cloud data in rviz. My point cloud data is like this. Can I visualize these point cloud data in rviz? or Can I create bag file by these point cloud data?

Can you clarify the format of the file? What does each column represent?
If your file has:
- the ranges or x/y coordinates of the scan from your lidar in the sensor's frame
- a time stamp for each reading (I suppose that's not "technically" a requirement)
- some odometry estimate ...

the you can just write anode that reads the file and publishes things to the correct topics (e.g. /scan, /odom, /tf, etc)
