For my old job at Emerald Works, I wrote a report based on a survey sent to leaders of various companies.
This is the source for the visualisations I made using D3.js. See and interect with them here: https://daikman.github.io/leadership_report
I wouldn't advise using this code for your own projects, as it's almost definately not the best implementation. It works though!
