Northwestern University Knight Lab is a community of designers, developers, students, and educators working on experiments designed to push journalism into new spaces. Out of this collaboration have come a suite of tools for creating highly interactive, beautiful representations of data. The suite includes JuxtaposeJS, a tool for juxtaposing changes in two images over time, SoundciteJS, in which audio can be embedded into a paragraph of text, StorymapJS, a clean, annotated map interface for storytelling, and TimelineJS, a timeline creator which beautifully integrates audio-visual data into its interactive format.
