Olli

Toolkit for converting visualizations into keyboard-navigable textual descriptions

Research themes: Accessible Data Analysis

Olli is an open-source library for converting data visualizations into accessible text structures for screen reader users. Starting with an existing visualization specification created with a supported toolkit, Olli produces a keyboard-navigable tree view with descriptions at varying levels of detail. Users can explore these structures both to get an initial overview, and to dive into the data in more detail.
