Any time property. Human births and deaths were chosen for development
mostly because of the size. Another imaginable example would be time and
place of scientific publications.

Next research question:
{q | instance_of(i, q) and has_time_property(i) and has_geo_property(i)}
In this case we know humans (q5) are things that have time
properties and geo properties. What are all the types of things that
have time and geo properties?
I'd say anything that has statements with p instance_of Q18635217
(Wikidata property for specifying a location of an event) as well as
statements with p instance_of Q18636219 (Wikidata property with datatype
'time'). Probably a lot.
But there is also the question what makes an "interesting" dataset. And
that the visualization in it's current state doesn't make much sense for
datasets with less than a few thousand items.
Make a great day,

Georg,
Nice viz! In your example you show births and deaths, so is your
dataset, {items with date of birth} \intersect {items with place of
birth}? In general are you thinking about visualising items that have
birth a geo-cordinate and a time-coordinate?
Yes that is correct, or to be more precise, all items that are
humans
(instance of Q5) and have both, a time- and geo-coordinate. So
if for
example an item would have a birth date specified but no place
of birth
(or the other way around) it won't be included in the extracted
births
dataset.
Oh, and something that I forgot to mention earlier: The
application is
quite performance intensive and is best viewed in Chromium (or
Chrome)
if possible.
Make a great day,
Max Klein ‽

Very nice, Georg! Looking forward to more data sets to
display.
