About the Site

These visualisations use a variety of open-source libraries, including Leaflet, Exhibit, JQuery, D3, Dimple, and Sigmajs, but have been chosen and tailored specifically for spatial, temporal and personal attributes. While these technologies are open-source, they have been adapted and developed for the specific purposes of this site by Niall O'Leary. The letters metadata used is drawn from a wide range of sources, both online and collected in books. Where links to letters exist, I have tried to provide this (you can explore individual letters via the 'Search' option and through the 'Letters' link in the menu). These visualisations use only metadata - sender, recipient, place of origin, destination, date. No letter content has been used.
