I do also use Python (pandas) partway down the page :) I'm just trying to show different tools to give people ideas about how much is possible with stuff that is already in /usr/bin/
If you were to ask my own tool preferences which I use for $DAYJOB: pandas for data cleaning and small data because I think that dataframes are genuinely a good API. I use SQL for larger datasets and I am not keen on matplotlib but still use it for graphs I have to show to other people.
Erk - readding it and busting the cache. After I put my kids to bed I will figure out what is wrong
EDIT: the reason it works for me is because I've got this config in ~/.sqliterc:
Apparently at some point in the past I realised that I mostly insert csv files into it and set that default.
