Trading Consequences - Interlinked Visualizations

The purpose of this visualization prototype is to provide a general overview of how commodities were discussed between 1750 and 1950 along geographic and temporal dimensions, as well as to show details on particular commodities or locations of interest. It was developed to help explore a large collection of historic data (163999 documents) on a meta-level and to facilitate finding documents that may be relevant for more detailed inspection.

The different visual components are interlinked: for instance, selecting a commodity from the list will update the map and timeline accordingly. Zooming into the map allows the exploration of locations and related commodities in more detail. Specifing a particular time range of interest, adjusts the map and commodity list accordingly. Selecting a document in the list view, opens the document at the digital archives.

You can find more information about how to interact with the visualiztion here. The visualization is enjoyed best with newer versions of the Chrome Browser - other browsers will not work.

The underlying data of the visualization comes from historic texts from the following sources:

This visualization is implemented in JavaScript using the libraries D3.js and jQuery.js.

This visualization was built as part of the Trading Consequences Project, a collaboration between Environmental Historians at York University and University of Saskatchewan, Researchers in Text Mining and Language Processing in the School of Informatics at the University of Edinburgh, software engineers from EDINA, and Information Visualization researchers at the University of St Andrews.
