https://usabilityhub.com provides word clouds (makes qualitative data more quantitative) as well as demographic reports, response times, and heat mapping visualizations per respondent.

Regarding the presentation logistics itself, UsabilityHub also provides public URLs that you can share with stakeholders (no passwords / walls to get through to see results).
