This interface was created through customization of the CartoDB mapping platform. After the spreadsheets containing the organized and formatted data based on the travel narratives were uploaded as datasets, the placement of the points and the journey segments was modified with customized SQL statements. The greatest change here was scattering all points that refer to the same location so that the markers would not overlap. Next, the info windows were modified within the CartoDB platform in order to display information according to a fixed format, and the appearance of the points and the journey segments was modified with standard CSS inputs.
There are plans for even more fine-tuning and customization of this platform, including the addition of a timeline, directionality arrows on the journey segments, and dynamic querying that will filter the data by multiple categories.
