So for Viet Nam; Denmark, Germany, Sweden and Spain are okay, but not Austria, Belgium and The Netherlands.
Interesting visualisation; the map is missing South Sudan though.

this is just how countries managed/refused treaties with each others, based on mutual interests, history, etc
Germans can enter Vietnam visa-free, while Vietnamese can't enter Germany visa-free. You find those one-sided visa-free agreements especially for many African countries.
Americans can go to many countries (even ones without a large tourism economy) despite being rather stingy with letting others in.
Far more important is assessing the likelihood that someone will try to permanently stay/work on a tourist visa.
UPDATE:
Just did a quick check on this (as it's a curious question) and it seems to be the case:
http://europa.eu/youreurope/citizens/travel/entry-exit/non-e...
"If your visa is from a "Schengen area" country, it automatically allows you to travel to the other Schengen countries as well."
Not in the EU as the Schengen agreement regulates the Visa rules for the entire Schengen area.
(They also have an unusually tasteful flag, that manages to represent the geography of the country without looking like a map.)
I didn't know about the Gambia, but there are others in English, or example "The Czech Republic."
Cool stuff!
Although, after the visa issue, many less well-off countries are far more restrictive on immigration laws. Guatemala, for instance, charges a per-day fine for visa overstay and won't let you leave until it's resolved. My daughter, born to a GT national, owes around $4000 in fines on leaving.[1] Can you imagine how it'd be if Canada/EU/US would be viewed if they didn't let illegal immigrants leave until they paid fines?
Guatemala also supposedly requires a local transit-license to drive here. Whereas you can get stopped by the police as a Guatemala tourist in Canada/US just fine, here, even with passport and drivers' license, you can be detained/fined. However I imagine this is selectively enforced.
1: We'll end up either getting local citizenship to eliminate it, or somehow negotiating a better deal.

1. No need for a bilateral agreement meaning too few people would be affected by this (think of: number of expats/tourists).
2. Historical reasons, e.g. due to colonialism. This could be true for your vietnam example since The Netherlands got colonies on now-Vietnames territory.
