Odyssey.js is an open-source tool that allows you to combine maps, narratives, and other multimedia into a beautiful story. You enhance the narrative and multimedia of your stories using Actions (e.g. map movements, video and sound control, or the display or new content) that will let you tell your story in an exciting new way. Experts can also add custom Templates and Actions by following the contribution guide. The tool is still under development and will include YouTube, Vimeo, Soundcloud, and Twitter based Actions. The library is open source and freely available to use in your projects.
