Suggest to please add a License, such as MIT or ISC. Thanks!

Done! I'm curious why, though? I mean why *this* notebook of the 50 or so I've published. Are you planning to use it? Or is this a more general suggestion?

Thanks! Although, strange, I don't see any license here at the top of the notebook. I'm planning on building something similar to this, and I'd like to copy some of the code verbatim, particularly around the data fetching and parsing for the Census API. I just wanted to make sure I wasn't infringing on any copyright laws. I generally hesitate to pull code from anywhere that's not explicitly permissively licensed. I think it's a great practice to add license across the board, but I'm using this one in particular as a reference example for some of my work. I will cite this of course as well!

Oops - I neglected to hit the Republish button; you should see it now. And thanks for the input on licenses. I agree with you; I've just rarely seen my work as something that would be used outside my own use. Maybe Observable is changing that.

I see it now. Thanks a ton!
