Updated March 25th, 2022: The main Voyant site has been having some unspecified server issues that seem to have knocked my corpus offline, so I have moved the project to one of the mirrors they recommend, voyant.lincsproject.ca

https://voyant.lincsproject.ca/?corpus=95a00aca24edf72f47ffd99c7798852d&stoplist=keywords-3d35d5a314b65bd07a8eb99c71aebd81

The Voyant Java application is available on their Github Repository: https://github.com/sgsinclair/Voyant

I did much of my work using the local server version; it works a bit faster, but provides no easy way to share the interactive results.
