[Question] Just use visualization

[CesMak]

Hey,

I just want to use the nice visualization nodes you have here. I already have a published topic /imu in my ros what should I do to just use your visualization?

I thought I have to simply launch:
roslaunch razor_imu_9dof razor-display.launch

But I got this error:

process[display_3D_visualization_node-2]: started with pid [30306]
