or add `unflatten` to the chain for a better layout:

Note: In cases of handling large datasets, you might encounter a "maximum recursion depth exceeded" error. To work around this, you can increase the recursion limit in your Python environment by adding `sys.setrecursionlimit(15000)` in the `lsofgraph.py` script.
