Through the visualization of parallel timelines, this application allows to explore different aspects of the history of the SCC (evolution of competences, turnover of the personnel, frequency of the meetings) within global history (Global Legal History, History of the Roman Curia, Pontificates). We enriched the original data with descriptive metadata, which provide information in case of uncertainty, unclearness and incompleteness of data. Since many inputs have incomplete information, we decided to use vis.js</hi><ref xmlns="http://www.tei-c.org/ns/1.0" n="17" target="ftn17" /> <hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt" xml:space="preserve"> and R, for working with both – the data in an advanced way and the graphic visualization in dynamics, which also allows to visualize the uncertainty, unclearness and incompleteness in a functional (R) and aesthetic way (JS + CSS). We also combined the data and controllers, as we want to let users choose the settings. </hi>
