<hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt">We consider that adequate historical contextualisation of data is necessary in order to avoid anachronistic or teleological biases and allow to interpret the results in scientific ways that correspond academic standards of historical research. To contextualize the SCC data and its metadata we developed visualization approaches that allow us to show our data not only as tables but also in interactive graphic format, to improve accessibility from the user perspective. There are various methods for visualizing historical data, focused on modern ideas of time</hi><ref xmlns="http://www.tei-c.org/ns/1.0" n="15" target="ftn15" /> <hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt" xml:space="preserve"> and space</hi><ref xmlns="http://www.tei-c.org/ns/1.0" n="16" target="ftn16" /> <hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt" xml:space="preserve"> that however don’t count uncertainty, unclearness and incompleteness of historical data</hi> <hi xmlns="http://www.tei-c.org/ns/1.0" rend="footnote_reference">.</hi> <hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt" xml:space="preserve">We stress on methods of visualization of unclear, uncertain and incomplete data for reducing the impact of modern gaze on time and history. We also aim to remain the complexity of the sources from the perspective of an historian, i.e. preserve the original data as presented in the sources even if unclear, uncertain or incomplete. This part of our project aims to extend the functionality of this kind of instrument with setting up the custom controllers, impossible to maintain in already existed tools and therefore make uncertainty, unclearness and incompleteness visible and accessible as an important specifics of the data. The principal languages we use for this part of the project are R and </hi> <hi xmlns="http://www.tei-c.org/ns/1.0" rend="background(white)" style="font-size:12pt">JavaScript</hi> <hi xmlns="http://www.tei-c.org/ns/1.0" style="font-size:12pt" xml:space="preserve">. </hi>
