+Example:
+
+ include('elements/report.html',
+ #required
+ 'title' => 'Page title',
+ 'items' => \@items,
+ 'data' => [ \@item1 \@item2 ... ],
+
+ #these run parallel to items, and can be given as hashes
+ 'row_labels' => \@row_labels, #required
+ 'colors' => \@colors, #required
+ 'graph_labels' => \@graph_labels, #defaults to row_labels
+
+ 'links' => \@links, #optional
+
+ #these run parallel to the elements of each @item
+ 'col_labels' => \@col_labels, #required
+ 'axis_labels' => \@axis_labels, #defaults to col_labels
+
+ #optional
+ 'nototal' => 1,
+ 'graph_type' => 'LinesPoints',
+ 'bottom_total' => 1,
+ 'sprintf' => '%u', #sprintf format, overrides default %.2f
+ 'disable_money' => 1,
+ );
+
+About @links: Each element must be an arrayref, corresponding to an element of
+@items. Within the array, the first element is a URL prefix, and the rest
+are suffixes corresponding to data elements. These will be joined without
+any delimiter and linked from the elements in @data.
