circular histograms

I was wondering that it would be really nice to be able to make
circular histograms in Gnumeric (aka rose plots or diagrams)

At least in geology, we usually make those plots in two ways: from a
dataset of (azimuth,length) of lines (geological structures), we
create the diagrams with the petals (histogram bin) weighted eitehr by
azimuth frequency or by line length. See the attachment for an
example. That is a "post-processed" version, where I joined the two
kinds in one figure. Normally we get the whole circle rose or the
upper half.
