# This is an example of an OpenDocument Chart.
#
# Opendocument charts are usually not found in the wild. They are intended to be
# subobojects of e.g. spreadsheets. But the KDE application called kchart
# (http://www.koffice.org/kchart/) is able to read and write ODC files.
#
# Kchart is able to understand a document without <chart:series>, whereas
# OOo misinterprets the label rows and columns. So if you embed the
# spectre-balance.odc file in an OOo Writer document, expect to see some
# oddities.
