We would also welcome you with open arms at https://github.com/saulpw/visidata =) Send us an email, or join us on freenode, twitter, etc, if you want to help out! I would love to onboard you.
Thank you for the reply! As I said to someone else, I'll dig into this first, then reach out if I see some area where I could potentially help out. (I wasn't expecting to get so many replies to my original comment here.)
