Earlier quoted context omitted.

I added some context through the links at the bottom of the map: you can go to http://migrationsmap.net/about.html or directly to the page where the data is coming from: http://www.migrationdrc.org/research/typesofmigration/global...

No, you need to have units on your data. Without units, numbers mean nothing. You select a country, and then you're presented with a list of other countries and some numbers. It's not clear that these are lifetime immigrants or permanent residents. There should be a title on the country info box "Total lifetime immigrants" or "Total lifetime emigrants", and ideally a legend at the bottom defining what that means. It'…

No, I don't NEED to do anything... That said, your comments are totally relevant, I will implement them.

Interesting...there is a huge migration from Brazil to China..can someone point out whats the reason?

I'm inclined to believe it's wrong data.

It could be there was some so-called return immigration, with Chinese-Brazilians going to China during the times of high unemployment rate on Brazil (as lots of Japanese-Brazilians did). But as a Brazilian I've never heard of that, so 50k sounds implausible.

Some data seems strange to me. Why would 123k mexicans go to pakistan? Or 30k mexicans go to Congo? http://migrationsmap.net/#/MEX/departures and I understand this is lifetime, but still those two destinations seem unlikely to me. fascinating map nonetheless.

Nevermind Pakistan, why would 2,626 Mexicans go to Greenland? http://migrationsmap.net/#/GRL/arrivals

Nice and interesting, well done! I also like the offline caching feature. The only tiny imperfection I see it's in the lines connecting two countries, I'd like to see an arrow so I know if I'm looking at arrivals or departures. Is there a way to filter the GMO database to see only the current migration flow (say, last 5 years)?

I have tried to add arrows at some point, but it cluttered the visualization too much (especially for countries where migrations are quite local : limited to border-sharing countries). That said, there may be a solution I did not think about.

How about narrowing lines?

I see various migrations lacking - f.ex. Polish to Brazil, and Vietnamese to Poland. why is that?

The reason is probably because the map is only showing the top 10 for each list of countries. Vietnam is probably not in the top ten for arrivals in Poland. You can easily verify this here: http://www.migrationdrc.org/research/typesofmigration/global...

there's said to be 30-40k Vietnamese in Poland, some say even 50k. also there's a huuuuuge Polonia in Brazil.

The blue arrow next to the arrivals and departures selection, acts like a radio buttion, but looks like an arrow. This is misleading... I was wondering why it said "Arrivals => Deprture" which looked weird... only after i clicked around, it was obvious that it was acting like a radio button.

I was also initially confused by that.

Maybe the arrow and the name of the currently selected item could be enclosed in a bounding box with a darker background, so as to more clearly show that it is currently selected.
