Paperscape is a visual map of the arXiv, presenting scientific papers as a galaxy-like landscape where each paper appears as a bubble whose size reflects its citation impact and whose position reflects its relationships to other papers. Built using force-directed graph algorithms and arXiv metadata, Paperscape allows users to explore fields such as physics, mathematics, computer science, and quantitative biology through an intuitive spatial interface rather than traditional search lists. The visualization reveals clusters, subfields, and research trends, helping users see how topics interconnect and evolve over time. Its strength lies in converting the overwhelming volume of arXiv content into a navigable, exploratory environment that makes patterns in scientific publishing immediately visible. While it does not replace conventional search tools, Paperscape remains a valuable companion for researchers, students, and science enthusiasts who want to understand the structure of scholarly domains at a glance.
