is a web visualization tool of Open Source Software (OSS) peer review process developed based on D3.js, a JavaScript library. This tool aims to summarize history of OSS peer review in many aspects for facilicating Software Engineering researchers and others who are interested in this process. Currently, ReDA visualizes peer review history of Android Open Source Project (AOSP), which based on Gerrit, an online code reviews for projects using the Git version control system.
