=head1 NAME
Bio::Graphics::Glyph::ellipse - The "ellipse" glyph
=head1 SYNOPSIS
  See L<Bio::Graphics::Panel> and L<Bio::Graphics::Glyph>.
=head1 DESCRIPTION
This glyph draws an oval instead of a box; otherwise it is similar to
the "generic" or "box" glyphs.  The width of the oval is determined by
the feature width, and the height by the -height option.

L<Bio::Graphics::Glyph> for a full explanation.
