In 1812, GWF Hegel published his Science of Logic. Two centuries later, one of his disciples put on Github an interactive visualisation of Hegel's work, which essentially takes the structure of the text and puts it into a visual map. Whether the visualization has any utility, I'm not sure. But it's fun to give it a quick spin.
