How do you capture things like charts or tables produced from long-running notebooks? Do you have a separate system to keep track of these? I prize notebooks with outputs in our data science repo since I can see the results of our analyses years later without having to re-run the notebook. In some cases, the notebooks don't even run anymore since our environment has moved on, but I can still see the graphs and read the text that was associated with that analysis.
