Visualizing a dynamic map with ros2djs

edit

Hello, I am currently using the "Visualizing a Map" to see the map created by my turtlebot robot and navigate in it, and it works fine. Now i would like to know if it is possible to see the evolution of the map, for example when the robot see an unknown part of the map. As it is, as the map is only loaded at the beginning, the ROS map is updated but the html map is not. Is there a way to refresh the HTML map regularly ?
