Leaflet.js is a lightweight, open source Javascript library that is widely used to create and share web mapping projects online. It is a great tool for creating an interactive map that can be embedded in a larger digital project. This workshop introduced the basics of setting up a Leaflet project and displaying a simple map with some data, using only a few lines of code. Because this involves a tiny bit of Javascript, Leaflet.js is suitable for folks who have some programming experience or are feeling adventurous about learning to code.
