Each circle in this visualization contains words that connect to one or more articles or media files in the Public archive. The size of the circle and the saturation of the color indicates the frequency each term is used. The list below shows the categories of data stored in the archive; these can be turned on or off to change the focus of the visualization. Clicking on any of the circles will open a listing of articles that relate to these terms, and clicking on the article titles themselves will provide direct access to the article content.
