I was looking for a guile-cairo example, so I gave gave this a try, by 
adding a "(use-modules (charting))" to those four 
lines, and running from the guile-charting-0.1.0
build directory with "env guile -s ../examples/height.scm".

It fails with
ERROR: Unbound variable: :write-to-png


Changing only ":write-to-png" to "#:write-to-png" changes the session to:


$ cat ../examples/height.scm
(use-modules (charting))

(make-bar-chart "Average Height at Iihenda JSS"
                  '(("Grade 9" (150 "Boys") (140 "Girls"))
                    ("Grade 10" (153 "Boys") (147 "Girls")))
                  #:write-to-png "/tmp/graph.png")
$ env guile -s ../examples/height.scm
ERROR: Unbound variable: :y-axis-ticks
$


This looks like a problem of the #: vs. : style of keyword-arguments,
but adding "(read-set! keywords 'prefix)" to the
example doesn't fix things, but simply changes the error to
ERROR: Unbound variable: #{:y-axis-ticks}#


All this using guile-cairo-1.3.91, cario-1.2.6, and fedora core's 
guile-1.8.0-8.20060831cvs
