Datawrapper is a tool that allows users to create simple, correct charts from data in just four steps: uploading data, annotating it, visualizing it, and embedding the chart. It is designed for journalists and aims to make data visualization fast and easy. Datawrapper charts are free, open source, can be hosted online or locally, and allow newsrooms to retain ownership of their data. The goal is to help journalists put numbers in context through data-driven storytelling.
