Display demography of Jewish communities

[josefspr]

On timeline: vertical hair moves with cursor and changes current time of populations. on selection of event - current time set to time of event. On map: Circles around places, radius interpolation of measuring points. http://www.therefugeeproject.org/ consider a way to display the 2 nearest population counts

[josefspr]

consider a mode of the map that does not show events, just the populations. before doing this we will need to add data to eastern part of the world.

[josefspr]

we also need an find an elegant way to display credit to the researchers that supplied the database.

I propose to implement these as a bubble map. The bubble sizes will correspond to population sizes as equally interpolated between the data points we have. Bubble colors will correspond with the point and map periods. Hovering on the timeline will animate the bubble sizes to match the hovered year. When we open a card event the map will show that event's year bubble sizes. Here's a mockup:

Please note that this will require more fine-tuning once implemented (scale, color, transparency etc…)

The bubbles look like the groups/annotation edges. Something more is necessary to clarify that these are populations. I think this mode should be toggle-able. Also I think we need a vertical hair on the timeline to clarify the effect of hovering or selection on the populations. Also possibility to view the numbers (lower and upper nearest count).

I see there is a vertical hair at the bottom its just very small...

I am attaching here a minor change that includes a more distinct outline for the population bubbles. Either way, this requires more testing on the actual dev environment:

As for max/min populations, we could maybe show that in the event card, like this:

[josefspr]

I am not sure about the cards that are quite full of info. Why not display numbers on map only on hovered or selected event, like 1800: 10,000 1850: 30,000 also, I think a toggle is necessary for this display, one, so people will understand what the bubbles, two, it load lots of visual information so it can be turned off

[mushon]

I really think it would be a mistake not to show this information visually (as a graph), I think numbers make very little sense here. As for what we will see on the map, I insist we should wait for the implementation and only then decide on the approach.

[josefspr]

ok, we'll wait for implementation
