We also have two standardized ones, Traditional and Simplified, now. Mainland China and some Chinese communities in Southeast Asia uses Simplified. Others like Hong Kong, Macau, and Taiwan uses Traditional. But, each place also developed some sub-variants characters.
Aside from that, there's quite a few different stroke scripts styles developed over the millennia. Also, there's variants of many characters used historically by different ancient kingdoms or for modern artistic purposes.
Because of history, of the more than 300 languages and dialects used in PRC now, a few, like Cantonese from Guangzhou, has its own regional usage of variant characters too.

This one is from my office.
