This is a d3.js visualization of US zip codes.
Original zip code dataset from Geocommons.
5MB shapefile with properties such as zipcode, state, name, population, area, more.

This converts it nicely:
topojson \
-p name=PO_NAME \
-p zip=ZIP \
-p state=STATE \
-o zips_us_topo.json \
zip_codes_for_the_usa.shp
Any luck finding anything @Oscarsgc?
In the same boat as you.. this topojson dataset is great, it's just seems to be missing Alaska (AK) and Hawaii (HI) which can be presented nicely with the albersUSA projection - as can be seen here: https://bl.ocks.org/mbostock/4060606
