visualgo was conceptualised in 2011 by dr steven halim as a tool to help his students better understand data structures and algorithms, by allowing them to learn the basics on their own and at their own pace. together with his students from the national university of singapore, a series of visualizations were developed and consolidated, from simple sorting algorithms to complex graph data structures. though specifically designed for the use of nus students taking various data structure and algorithm classes (cs1010/equivalent, cs2040/equivalent, cs3230, cs3233, and cs4234), as advocators of online learning, we hope that curious minds around the world will find these visualizations useful as well.
