I'm sorry, but I'm not familliar with the finer
details of CSS.

How about using a transparent 1x1 spacer with the ALT
tag as a single ascii char in the background color?
But that reintroduces the spacer ...

Or you could use a table containing separate tables
with different width (presumably equal to
percentages), as in
http://www.pageresource.com/html/table5.htm, and
without &nbsps; in the table cells. So you'd have:

bar chart table with width 100 
  for each color:
  empty background coloured table with width equal to
that color's percentage

I believe one has to excecise great care with
parameters to get it to work reliably on older
browsers, but hey, if your stuff validates, it should
work ;)

Cool. The more valid pages on the web, the better ;)

I'll try to get it to work soon.
