The 1px spacing seems difficult using the 'heatmap' prefab that ships
with ploticus (http://ploticus.sf.net), I've used
% pl -prefab heatmap delim=tab data=stdin x=1 y=2 ycats=yes \
contentfield=3 rectangle="4 1 10 50" symbol="shape=square \
radius=0.069" colorlist=black,black,xrgb(800000),xrgb(505050),\
xrgb(bbbbbb),xrgb(ccff00) xcats=yes -png -pagesize 100,100
on the result of `perl pl-prep.pl < w3c-member-validity-data.tsv`
(where the Perl script does some grouping and sorting). I think more
sophisticated visualization would require writing a new ploitucs
script. I don't think the different spacing and color make it much
better...
