I made this deck containing Chinese characters of:
These are ranked by both HSK grade level AND frequency in ascending order of difficulty and occurrence. (Why? Characters for vegetables, for example, rank low in frequency but high in HSK)
Having said that, since this includes the entire set of unicode characters that can be displayed by a computer (80K of them), only really the first 10K or so are annotated. The remaining 70K are mostly archaic or esoteric variants that have very little information to them.
Note: I don't recommend this deck for beginners. It's sourced from Unicode, which is an organization that only cares about displaying as many characters from as many languages as possible on your computer screen. There's a lot of technicalities in their data that could confuse people who don't already have a good grasp of Chinese. I personally only use this deck so I don't forget characters while I'm living outside of China.
