How would YaleDH like Pixplot to be cited?

I'd like to use PixPlot in a paper and want to make sure I'm citing it correctly. @pleonard212 and @duhaime, would you be able to provide a suggested citation? 

(I apologise if this information is elsewhere; I've searched and wasn't able to find it. And the 'View Project' link at https://dhlab.yale.edu/projects/pixplot/ seems to be down.) 

Many thanks!
