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?

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.
