(also add to popstats).

Not necessarily fully mobile compatible, however should at least be legible on smaller screen widths.

Would you preffer to use the Robinson map projection instead the Equirectangular one?

It would involve loading the packages d3-geo and d3-geo-projection.
Best regards!

I know you used the historical county polygons created by CShapes but could we add a lines layer so we can show the official UN disputed boundaries as we did for the popstat one?

currently sharing on facebook looks like this using the old url and thumbnail

The map should use same red/green branding colours as population-change chart

When zooming at https://github.com/unhcr/dataviz/blob/master/js/worldtopo.json one can see that the topology is not maintained.

Ways to simplify polygons while maintaining the topology are discussed here:
https://gis.stackexchange.com/questions/185040/simplify-geometries-but-keep-them-contiguous
https://gis.stackexchange.com/questions/178/simplifying-adjacent-polygons/
https://trac.osgeo.org/postgis/wiki/UsersWikiSimplifyPreserveTopology
https://trac.osgeo.org/postgis/wiki/UsersWikiSimplifyWithTopologyExt

This is in view of another possible improvement, namely to render zooming possible (in a visually appealing way)

Zooming and panning are very common functionalities in webgis, even for thematic world maps. This would allow to see better the data in small countries, or to have a regional focus. It is also interesting for mobile users (smartphones with small displays).
It would require to fix this:

Perhaps icons for increased and decreased should be swapped.

Currently the json creates a polygon with a hole for the Baltic countries in 1991. In fact two polygons are stacked, one being incomplete.
See screenshots:

This should be as follows (taken from my peaceprism repository):

This issue would be fixed by using the file in this commit:

Hi For the map -- using an absolute measurement in a choropleth is a semiologic error - (unless it would be a choropleth with polygons of a similar size) -

Either we convert the value to be displayed to a % of change in comparison of previous year - the it's a ratio and we can keep a choropleth -

or better we keep absolute number of persons increase/decrease and use proportional symbols with a color code to encode the relative percentage of the increase in comparison with the existing population

When a country is selected, the total chart axis should update when toggling between country of origin and country of asylum.

From @vidonne - The arrows on the dropdown aren’t clickable. You actually need to click on the menu itself. Better to make the arrows also clickable.

To recreate

1. Click on Russia
2. Mouse over 1996 - increases correctly shows 246k
3. Mouse over 1995 - increases still shows 246k when it should show zero.

Would be a nice touch 😄

We need to make sure this visualization sits nicely on the data portal once it's embedded.

In case it's published externally, give a trail to the Open Source part.

To support effective embedding in the data portal, which uses an iframe that must be resized according to the visualization

Wouldn't it be better to update the worldtopo.json
replacing
"COWEYEAR":2012
by
"COWEYEAR":2016
?

to be fixed by stretching height of total bar overlay over .yearLabels

There are a few minor issues blocking a proper release of this:

• Bug with increase/decrease text on year slider event #28 (Curran)
• Disputed International borders #50 (Matthew)
• Finishing Touches for Data Portal Embed #69

One issue is that the map gets cut off on the left and right. Let's try using the SVG viewbox attribute to have the SVG fill the available width.

The landing page should be a listing of UNHCR data visualization products, with links to each.

The visualization currently at the root directory can be moved to a subdirectory and linked from the index.

The data can be updated here, so it goes to 2016.

At the bottom of the page, it leads to a broken link. Perhaps best to remove?

still uses old colours on transition.

Some operations could be interested to replicate the same dataset visualization with more details (extracting for instance from their registration data):

• Adding Level1 admin countries
• showing details by month
• showing additional details (family size, occupation, education, sp.needs, age&sex breakdown...)

Building on this viz, it could be interesting to have a replicable example with some documentation.

See for instance: https://zanmat.github.io/IDPDisplacement/
