I don't believe there are currently any Julia packages that do this, but you could utilize or extend Gadfly's D3 engine with polymaps.js (http://polymaps.org/). Assuming you have a set of lat/lon pairs in GeoJSON, you could essentially create a function that transforms your lat/lon coordinates to those that would fit on a 2D canvas viewport.
This is essentially the approach that the ggmap R package called uses, which is built on top of ggplot2 (the equivalent of Gadfly for R). Let me know if you have any luck, I'm interested in this capability as well.
