I wouldn't rely on the link above. They are just a travel company, who posts information regarding limited range of countries and nationalities, where they provide visa assistance. Furthermore visa requirements are subject to change quite often, and there is no guarantee, they post up to date information.
You can check whether you need a visa to a certain country in TIMATIC database. It is the only complete, trustworthy, daily updated source of information for travelers, arriving by plane. All airlines use their database to determine, whether a passenger needs a visa, or not. If there is written, you need visa, but you have opposite information from other sources, they won't let you in the plane anyway, no matter how hard would you try to prove your rightness. Although even TIMATIC has had a few errors and gaps, but that was quite complicated cases with unusual types of passports, so for 99.99% of you the information is completely trustworthy.
I want to notice, that visa requirements for people arriving by air and overland are not always the same. So if you find in TIMATIC, you don't need a visa, it concerns to those, who arrive by air solely. Some countries exempt air passengers from visa, while demand overlanders to have a visa in advance, or opposite.
Actually, the access to TIMATIC database is paid. But still there's a trick, how you can get it for free. Follow the steps:
1. Type in wikipedia - visa policy of (country name)
2. Don't read the article itself (wikipedia has many errors), but go to the bottom of the page instead. You will find a list of the links there. Choose a link, which looks like that "Visa Information". Timatic. IATA."
3. Click the link, and you will find comprehensive TIMATIC visa information about a certain country, exactly the same, which an airline agents have. Like that:

Learn to read the information correctly and don't miss the crucial details. For example, some countries are visa-free, but they require you to have a hotel reservation or onward ticket in advance. And if you don't have, an airline deny you from boarding the plane.
