rviz run saved messages

edit

Hello,

I'm running a program that sends visualization messages, like the ones in the basic shape tutorial. While running the program I saved the messages with rostopic echo /visualization_marker > myfile.txt. I'm looking for a way to display thoose messages in rviz, is there such a way? I tried rostopic pub /visualization_marker visualization_msgs::MarkerArray -f myfile.txt, but i get ERROR: invalid topic type: visualization_msgs::MarkerArray. While rviz displays this is the topic type.

Kind regards
