Odyssey.js is an open source library that enables creators to build interactive stories on the web without coding skills, making map-based storytelling easier to develop. It features a sandbox for non-coders and coders alike to test its capabilities using Markdown markup language. The JavaScript library can be used to create complex interactions for map-based storytelling, allowing developers to visualize data-driven stories in an easy-to-use format. With the support of the John S. and James L. Knight Foundation, Odyssey.js aims to empower creators to bring their stories to life and make interactive storytelling more accessible to a wider audience.
