I've been

a) Playing with Datawrapper as a tool for displaying data here on Inkstain, and

b) Thinking about Albuquerque's aquifer as bad summer river flows force us back onto groundwater

(City #2, in the North Valley, is one of a quartet of groundwater monitoring wells drilled in the late '50s as Albuquerque's population and groundwater pumping began to grow. I use it for big picture attention because it's reasonably well placed to give a good rough picture of what's going on, and has a nice long time horizon.)

update:

Locator map was super easy in Datawrapper.
