NAME

Devel::WxProf::Treemap - Calculate Treemap for wxprofile

DESCRIPTION

This is a modified/rewritten version of Treemap. The main difference is, that the SPACING and PADDING parameters can take hash refs in the following form:

{
    top    => 5,
    bottom => 5,
    left   => 5,
    right  => 5
}

This allows for creating different spacings/paddings for each side, thus eases top-aligned labeling.

Note that treemaps with spacing and padding may be misleading - even more if spacing/padding is not (visually) equal on all borders.
