collection of topojson maps?

[jayeckles]

Anyone have a link to a collection of useful topojson maps (the format that can be used in the Shape Map Visual)?  I've found tools that will let you create these, and I've even found a US map that contains counties but no useful ID.  

Surely someone has a collection of common maps already in topojson format.  I'm looking right now for US zip codes, US counties (perhaps ID'd by FIPS), and US congressional districts.  

Thanks!

I finally had a chance to look more into this, and I have posted a TopoJSON file with Alaska and Hawaii shifted like it is with "Albers USA". Even as a custom map though, you can still select other projections like Mercator, and the Alaska/Hawaii shift is preserved.

@deldersveld How do I get a copy of this TopoJson US Map with zip codes ?

I loaded up your 20m US Counties map into the Power BI drilldown chloropleth map, added the GEOID from the file into my database to correspond with the correct county I wanted, did the same as well for the states, and gave each County/State combination in my access database a unique ID. However, when I try to filter out a specific county in a specific state, the map will populate all of the counties in the US with the same county name even though if is not in the correct state. Do you know a way to only have it display only the county that is in the state that I set a filter for?
