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.

        Georg
