The Trace The Trace is excited to announce the launch of its Gun Violence Data Hub, an initiative created to provide data for newsrooms around the country. The Data Hub went live with its site in early November. Made up of three parts, the site offers a help desk, reference material and resources, and an upcoming data library. The live help desk is staffed by three journalists who will field questions, clean and analyze data, and offer information to bolster coverage across the nation.
