  • Data Source: Louisa Co. Burnley Slave ListsApplication: GephiLayout algorithm: Dual CircleContent: Slaves, Owners, and PurchasersNotes: This shows the graph at a zoomed out level, where clusterings can be seen, but no specific data points. The four central densely linked nodes are slave owners or purchasers.

    13. 13. Overview<br />Discuss Ramsay, “In Praise of Pattern,” to explore ways of modeling and visualizing narrative<br />Look at some other examples<br />Discuss graphablepatterns in the Shahnameh, in preparation for hands-on work Thursday<br />
    14. 14. In Praise of Pattern<br />Ramsay argues that, in addition to the quantitative theorems of graph theory, graphs make good visualizations<br />They help you notice things, patterns<br />See version with images<br />http://studio1.shanti.virginia.edu/~rca2t/dataesthetics/04-05/ramsay-2005.html<br />
    15. 15. Graph Theory<br />The Geometry of Posistion (actually coined by Leibniz)<br />Reduces things to “vertices” and “edges”<br />Or “nodes” and “links” (dots and lines)<br />Theorems concern features such<br />number of nodes<br />number of edges<br />number of edges per node<br />“degrees” of separation between nodes, etc.<br />
    16. 16. Euler’s Solution to the Seven Bridges Problem<br />3<br />It becomes clear that nodes with with odd numbered links are a problem – if you come back to it, and aren’t finished, you are stuck … <br />Vizualized in this way, the problem becomes one of drawing the picture without retracing any line and without picking up the pencil.<br />3<br />5<br />3<br />http://mathforum.org/isaac/problems/bridges2.html<br />
    17. 17. Shaded Similarity Matrices<br />“You take a set of data measurements for a set of classes and use it to create another table that expresses degrees of proximity among those measurements. . . <br />“You then reorganize those values so that “more similar” values are adjacent to one another, assign each value a color, and arrange them in a grid.”<br />

    19. 19. Ramsay’s Application<br />Correlate graph properties with genre for plays<br />5 properties: Distinct, Total, Singles, Loops, and Switches<br />4 genres: Romance, Tragedy, History, and Comedy<br />“Low-level” vs. “high-level” properties<br />Method<br />X and Y axes both show plays, colored by genre<br />Each cell in the matrix is shaded according to similarity in terms of low-level properties<br />Low-level properties are added successively and the order of plays is changed to find clustering<br />
