Hello, I'm trying to figure out how to visualize the RPL DoDAG that's been formed. It looks like some projects involve using MATLAB, but that would require modifying the NetSim source code, which I want to avoid. Do you happen to know of any workarounds or alternative solutions? Thanks!
The DoDAG formed in an IoT RPL network can be visualized using the RPL DoDAG Visualizer utility explained:

This is a python-based utility; it uses the network configuration file, packet trace, and Wireshark logs to generate a DoDAG plot which includes information such as the device names and RPL ranks.
See https://www.tetcos.com/file-exchange.html under IoT, there is some documentation
There are multiple ways to visualize DoDAG formation in NetSim: (i) Using NetSim packet trace and/or Wireshark capture (ii) Using Python utility, and (iii) By interfacing with MATLAB.
Option (i) is not that easy and it requires you to look into large trace file and Ranks in Wireshark and form the DoDAG manually and visualize it over time.
The python utility for the visualization of DoDAG can be run after the simulation completion. Here is the link on how to use the utility https://support.tetcos.com/support/solutions/articles/14000134056-how-to-visualize-the-rpl-dodag-in-netsim-iot-simulations- . The drawback here is that you will not be able to visualize the DoDAG formation over time. You can only see the final DODAG.
When you interface with MATLAB you can see the DODAG formation over time. However, that will require a small amount of MATLAB code.
