nitpick: bug tracker chart scale

[Luís.Marques]

This might be nitpicking, but I believe aesthetics are important 
too: consider removing the three decimal digits present in the 
bug count chart of http://dlang.org/bugstats.php . After all, 
there are no fractional bug reports. (I would do it myself if I 
had access to the source code, but I imagine puremagic.com's code 
is not available).
