It's not very reliable data.
They took the similarity vectors from the job postings, not from resumes, so rather than "what you're likely to know", they computed "what an employer is likely to want at the same time as wanting something else", and then declared that a similarity due to an already skewed cosine similarity metric. This happens because employers are more likely to copy other, similar job postings, or other job postings for companies in a similar business as them, or those of a company whose employees they wish to hire away.
They claimed that they tried using resumes, but that the resulting data was not as "clean"; uh... duh?
This visualization was not actually very useful, unless you are trying to design a resume to get yourself hired, regardless of your actual current capabilities.
