David, I think you have colors reversed?

" This is especially revealed in the choices of data analysis tools by BI professionals (dark blue) and data scientists (light blue) in the chart below taken from the EMC report:"

Should be:
Dark blue -- Data Scientist
Light blue -- BI

also the percentages don't add to 100 in either case (you can spot this just by eye-balling)... and the way the data are presented is not optimal for the comparison - bar length should correspond to density or proportion rather than count since sample is unbalanced. Bit of a fluff up from a now "enterprise level" data company?

Ah because individuals can make multiple responses in the survey... my mistake

Thanks Jim & Wei, you're right -- I fixed the annotations in the post above.
