Did you did "python -m SimpleHTTPServer" on openspendingjs' root? I just
double-checked if I haven't forgot to commit any files, but everything

For example, check
It returns me 10 entries, but the first 3 are from the Department of
Health, and there's no guarantee that these 3 are all of its entries on
2012 (i.e. there might be one as the 11th element).
What I would like to get is "The 10 first entities of that dataset on
2012". It doesn't matter if the Department of Health has 3 or 300 entries,
I want them all.
Does it make sense?

Yes. For example, Slovakia's datasets have only yearly data, at January 1st
of each year. If I cut by only that year, the visualization looks awful.
Just a bunch of dots (or bars, or whatever) on that day. So I need to cut
by a range of years, so I can see the progress.
The problem is: the API doesn't have something like cut=time.year>2010. My
workaround is to do cut=time.year:2010|time.year:2011|time.year:2012. It
works for now, but if we imagine having a range slider, it would be good to
be able to select a range in months as well (not only years). It breaks
