Set style fill transparent
Some terminals support the attribute transparent for filled areas.
In the case of transparent solid fill areas, the density parameter is
interpreted as an alpha value; that is, density 0 is fully transparent,
density 1 is fully opaque. In the case of transparent pattern fill, the
background of the pattern is either fully transparent or fully opaque.

Note that there may be additional limitations on the creation or viewing of
graphs containing transparent fill areas. For example, the png terminal can
only use transparent fill if the "truecolor" option is set. Some pdf viewers
may not correctly display the fill areas even if they are correctly described
in the pdf file. Ghostscript/gv does not correctly display pattern-fill areas
even though actual PostScript printers generally have no problem.
