Visualizing bag files using d3.js

I wonder if there is any previous work for visualizing bag files using d3.js. I know I can convert them to csv but even in that case they differ somewhat from the normal csv files. Any hint is really appreciated.

You could publish the contents of the bag using rosbridge:

And then use roslibjs to interface it with d3.js:

If you want the data in a different flat format, you could use the rosbag API C++/Python to access the bag and then write it out to something else:

Hi @William can you please provide more details like the commands I should run in terminal? I am new to ROS and find this answer very high-level for me. Is there also a similar work of visualizing bag files using d3.js you can link me to? I've been googling but it was unsuccessful

I don't have time to walk you through it, but I'd recommend following the tutorials for rosbridge and/or roslibjs. I'm not aware of any out-of-the-box integration between d3.js and ROS. You're going to have to do some legwork and figure out what has already been done and what still needs to be done.
