Hi Markus, Denny and Wikidatans,
Thanks. I opened only the first link in your email, Markus, and I've
waited for 5 minutes and there's no loading happening.
I only see this on the left and it's static:

ViziData 1.0
There's only whiteness in the frames on the right - all viewed in Chrome.
I tried loading this link also in Firefox and the same thing happens.
Denny - any insight, please, into this from this side of the "pond"?
Thank you.
Regards,
Scott

Thanks, Markus and George,
I could only see a few controls in the upper left corner in
Chrome in
most of the links you both shared, except the video demo,
George, did
come through.
You need to wait until the loading is finished before you can see
the map (the loading activity is indicated on the left when you open
a page). Especially the "items" dataset that many links point to is
pretty big. There are more than 2 million items displayed and
filtered dynamically in this dataset, so the UI is not super-smooth.
But then again it allows you to view more than 10% of Wikidata's
items on a single screen :-)
Regards,
Markus
This is an exciting CC data which I hope will articulate with
something
like Google Earth, for example, and for a variety of STEM
research foci,
and in many languages.
Thank you,
Scott

Hey,
Thanks, Georg, that's really interesting. The added feature to
inspect each element to see the items there is really
useful. It's
great that it works at high zooms now with the map in the
background: I have spent some time exploring my own
vicinity for
people born there. As before, it works most smoothly for me
on Chrome.
You can see so many things in these maps depending on how
you look
at them. Here are some views that I found very interesting.
If you
click the links, it will always reload the data, so I am also
describing how to make the settings manually.
(1) "Popular places": the map of things that have articles
on at
least 20 Wikimedia sites:
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=items&l=en&f=1&e=20_336&c=false&g=0.5&h=1.2&o=1&p=3&x=23.37890625&y=28.998531814051795&z=3
Item data set with interval narrowed down to 20-336. You
can narrow
this down further by sliding the left boundary of the
interval at
the top towards the right. The 1004 most popular locations
on Earth
are those with at least 96 sitelinks (as fewer items are
returned,
it is a good idea to increase the Size setting under Map
Settings to
see them more clearly). If you look at the things with more
than 32
sitelinks, Italy somehow stands out among the rest of the
world in
terms of coverage. Even small villages there seem to be
covered in
many projects (why?):
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=items&l=en&f=1&e=32_336&c=false&g=0.8&h=1.2&o=1&p=3&x=27.509765625&y=41.21172151054787&z=4
(2) Orphaned items in Wikidata:
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=items&l=en&f=1&e=0_0&c=false&g=0.5&h=1.2&o=1&p=3&x=23.37890625&y=28.998531814051795&z=3
Obtained by decreasing the interval to "0-0" in the items
view. This
one has really interesting patterns ... you can see which
countries
have imported larger sets of items that are not from Wikipedia
(having the Netherlands inside your map view slows down the
browser
considerably ;-). But it's also interesting to zoom in to
some areas
with few orphans to see what they are (spam? remains of deleted
pages? something added by single users for some reason?).
If you
zoom all the way in to Amsterdam with grid size 0.2 you can
recognise the structure of the channels:
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=items&l=en&f=1&e=0_0&c=false&g=0.2&h=1.4&o=0.9&p=3&x=5.040321350097656&y=52.3465610683968&z=12
(3) People born between year 2BCE and 31CE (births dataset with
interval set appropriately and increased grid size so you can
recognise the few remaining points).
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=1&m=humans&l=en&f=1&e=-1_31&c=false&g=2.7&h=1.2&o=1&p=3&x=78.3984375&y=25.005972656239187&z=2
This is nice to find errors since there are very few people
at this
time, but you can easily enter such a date wrongly if you
type a
date as something like "February 15" ;-).
(4) Mortality peaks around World War 1 and World War 2:
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=humans&l=en&f=1&e=1700_2015&c=false&g=0.9&h=1.2&o=1&p=3&x=-92.021484375&y=39.41922073655956&z=5
"Deaths" dataset zoomed in at North America. You can
clearly see the
blue peaks of death around 1918 and 1945, but you can also
see that
these increased deaths happened elsewhere (not in North
America):
the green bars are fairly smooth. Zooming in to a smaller time
period of 1736-1883 on the same map, you can see that North
America
also had a peak in fatalities around 1864 that did not
affect the
remaining world:
http://wwwpub.zih.tu-dresden.de/~s5219191/vizidata/#d=0&m=humans&l=en&f=1&e=1736_1883&c=false&g=0.9&h=1.2&o=1&p=3&x=-92.021484375&y=39.41922073655956&z=5
Cheers,
Markus

I'd like to once more draw your attention to ViziData
[1]. The
project
has matured a bit since I first brought it up here a
few months ago.
Most notably there is now an underlying tile map
providing some
orientation better integration and interaction between
map and
timeline
and the possibility to list items aggregated in a map cell.
I created an overview page [2] for the Wikidata
Visualization
Challenge,
which can aid as quick reference for usage of the
application
(although
it is pretty cluttered). The version linked on that
page is my
submission to the challenge and already outdated
though, the
most up to
date version should usually be found on the link in
this mail [1].
There are only 2 new datasets, one is all locations
that have a
statement about their populations, however that needs
some more
work and
fine tuning. The other is any item that has a
coordinate location
statement, filterable by the number of interwiki links.
It shows a
pretty good coverage of the world, bring some patience
though
because
the 60mb json can take some time depending on the
connection. Also,
slower hardware might get a bit exhausted going through
the ~2.1
Million
items.
I guess one can imagine various use cases for the
application. For
instance, here is the people who died in the
Netherlands in 2015 in
Vizidata [3]. Be aware however, that those haven't
necessarily been
Dutch and also it doesn't include Dutch people who died
somewhere else.
Comparing with Gerards list [4] there seem to be quite
some people
missing. That's mainly because items that don't have
both a date of
death and a place of death statement are dropped from
the datasets.
Maybe it would be an option to include country of
citizenship as a
fallback but it could lead to slightly incorrect
representation
of the
data.
I hope this tool can provide some interesting insights
and help to
illustrate where there is most room for improvements in
our data
base.
Feel free to comment if you have questions or
proposals, or maybe an
idea for a dataset that you would like to see in ViziData.
