Hi, I'm assuming that by 'Topic Visualization' you mean visualizing various topics subscribing and publishing. In that case I suggest you to take a look at http://wiki.ros.org/rqt_graph

If what I'm assuming is wrong, then I need more info that topic like what is being published/subscribed, etc.

Hope this answer fulfills your need.

Thank you!!

My job is to display the plot on the web and get bag files, but as I read, I don’t need them for topic visualization. Am I correct?

From what you said so fa r I understand that you want to use the data from the topic of interest to visualize in the web right?

in that case, You can use [ROS bridge server package] (http://wiki.ros.org/rosbridge_server) and use ROSlibjs to visualize the data in the web. The data of choice can be anything. For example, you can subscribe to a topic that publishes live feed of Images from a webcam and you can visualize it in Web via rosbridge_Server and roslibjs.

hope this explanation helps.
