Mostly a placeholder, it currently shows a filled oval. If you choose a bump of 0, the ovals will overlap, to give a cloud effect. =head2 OPTIONS There are no glyph-specific options. =head1 BUGS Please report them. =head1 SEE ALSO L<Bio::Graphics::Panel>, L<Bio::Graphics::Glyph>, L<Bio::Graphics::Glyph::arrow>, L<Bio::Graphics::Glyph::cds>, L<Bio::Graphics::Glyph::crossbox>, L<Bio::Graphics::Glyph::diamond>, L<Bio::Graphics::Glyph::dna>, L<Bio::Graphics::Glyph::dot>, L<Bio::Graphics::Glyph::ellipse>, L<Bio::Graphics::Glyph::extending_arrow>, L<Bio::Graphics::Glyph::generic>, L<Bio::Graphics::Glyph::graded_segments>, L<Bio::Graphics::Glyph::heterogeneous_segments>, L<Bio::Graphics::Glyph::line>, L<Bio::Graphics::Glyph::pinsertion>, L<Bio::Graphics::Glyph::primers>, L<Bio::Graphics::Glyph::rndrect>, L<Bio::Graphics::Glyph::segments>, L<Bio::Graphics::Glyph::ruler_arrow>, L<Bio::Graphics::Glyph::toomany>, L<Bio::Graphics::Glyph::transcript>, L<Bio::Graphics::Glyph::transcript2>, L<Bio::Graphics::Glyph::translation>, L<Bio::Graphics::Glyph::triangle>, L<Bio::DB::GFF>, L<Bio::SeqI>, L<Bio::SeqFeatureI>, L<Bio::Das>, L<GD> =head1 AUTHOR Allen Day E<lt>day@cshl.orgE<gt>.
