Layout

Note that of the ~1.1 million codepoints under U+10FFFF (the current cap), ~900K are unused, ~130K are private use, and only ~100K are general-purpose graphic codepoints (about half in BMP).
Grouping used below is somewhat arbitrary, but looks halfway sensible
For more on planes, see http://en.wikipedia.org/wiki/Mapping_of_Unicode_characters#Planes

Mouseover shows a range's codepoint range, links are to unicode.org PDFs.
Nameless gray blocks are reserved, unused or restricted areas, and show their size.
If we are showing a single codepoint above, the range it is in is bolded below.
