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?
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,

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