Onodo is an open source network visualization and analysis tool for non-tech users. Onodo [https://onodo.org] is a product designed by experienced journalists for non-technical users that haven’t used network mapping tools before. It intends to be an effective tool for storytelling, a platform able to map, visualize and analyze and communicate complex information by people with storytelling needs, especially journalists that work with small or medium small focused databases. Behind this tool is Civio Foundation [https://onodo.org], a Spanish non-for-profit news organization that operates at the intersection of technology and journalism, and that was recently awarded with the Best Investigation of the Year (small newsroom) in the DJA 2016 for Medicamentalia, a data-based investigation about global access to medicines: http://medicamentalia.org/en/ Main features Onodo aims to facilitate the creation of network visualizations in very few steps. User workshops made its creators aware of the importance of immediate feedback when building a network, especially for users that need to learn its most basic concepts. Hence, we implemented split-screen real-time editing in Onodo: changes in the bottom spreadsheet-like component of the editing screen gets reflected automatically and in real time in the visualization at the top of the screen. Users can edit the information on the editing interface or import a file and in just two clicks the network will be ready. Network data visualizations have been implemented using state of the art visualization libraries (D3.js 4.0) for optimal performance and aesthetics. Visualizations can be customized to include pictures and descriptions, and different colours, sizes, thicknesses and patterns can be used to reflect dynamically the underlying data. Users can also embed them into any website just copy-pasting an html code. Additionally, for those interested in graph theory, Onodo includes a network analysis module so that the most important nodes and relations can be highlighted, distance between any two members calculated, and clusters of tightly connected members visualized.

Technologies used for this project:

Technology-wise, Onodo relies on well-known open-source components and libraries, mostly Rails 4.0 as web framework, PostgreSQL as database and Backbone.js as Javascript framework in the browser. Network data visualizations have been implemented using D3.js 4.0.
