Basically, there are more people living in a circle that encompasses India and China (and hence lots of other populous parts of Asia like Indonesia) than there are in North America, South America, Europe, Africa and Australia combined.
There's always a balance between how refined of data do you make. Part of this is dependent upon your audience (note that most people that use the internet reside in a location that has a dominant Abrahamic following).
This doesn't look like discrimination to me...
It is hard to say how to subdivide without becoming too busy. Maybe you could take countries with big populations and do a breakdown on their classifications. So specifically China and India, but maybe a few more. But that's not as visually appealing.
Looking at the pattern of cultural clashes around the world, it seems the there are three incompatible belief systems, Christianity, Islam, and CBT.
"Mixture of Buddhism, Taoism, Confucianism and Chinese folk religion" - China "Mixture of Buddhism and Shintoism" - Japan
Hinduism. I assume your miss was inadvertent.
Anyone got stats on how religion growth/decline rates are affected by economics and population size? I wonder if it is similar to how first world nations pretty much all have below a 2.0 population growth rate. Does the data suggest that as we become better off there's a correlation to less religion?

For example, Australia [1] saw a 9% decline in Christian religions between 2011 and 2016, and a corresponding 7.8% increase in non-religious over the same period.
France, to randomly choose another, shows a 15.9% drop in Christian religions between 2010 and 2016, and a 7.6% jump in non-religious over the same period.
