the smallest boundary in the 1-year acs files is public use microdata area
(puma), but the 3- and 5-year public use microdata samples (pums) go down
to some counties, i believe..

i think you just need to download the census bureau's shapefiles for the
geography you want to map

at the point you have a shapefile and you have created the data that you
actually want to map, maybe start exploring your mapping options in R here--

there's lots of people working with the ACS in R
