Extracting mutation and Mutation spectrum

Question

[realtreeecat]

Is there any tools or packages which can help me extract mutation information and essentially plot them to know the occurrence frequency of mutation or visualize the mutation spectra?

I have 1) Merged vcf file for all my sample information , 2) A jsonl tree information with annotated mutations and 3) a Mutation annotated (MAT) proto buffer file.

Which of these files are commonly used to generate mutation information and possibly visualize the mutation spectrum? Thank you
