  3. 1. Scatter Plot • Axes: two interest measures. • Color (gray level) – a third measure. Figure 1: Scatter Plot[1]

  4. Two-key plot • Color – Order, the number of items contained in the rule. Figure 2: Scatter Plot[1]

  5. 2. Matrix-based Visualizations Figure 3: Matrix-based visualization of two measures with colored squares[1] Figure 4: Matrix-based visualization of two measures with colored squares (reordered)[1]

  6. Matrix-based Visualizations • Explore different antecedents which have a similar impact on the same consequent in terms of the measure used in the plot. • X-axes – consequent itemsets. • Y-axes – consequent itemsets. • is the selected interest measure for the i-th rule.

  7. Matrix-based Visualizations 3D Bars Figure 5: Matrix-based visualization with 3D bars[1]

  8. 3. Grouped Matrix-based Visualization • Columns -- antecedent groups • Rows – consequents • Color – aggregated interest measure • Size of ballo0n-- aggregated support Figure 6: Grouped matrix with k=?[1]

  9. 4. Graph-based Visualizations Figure 8: Itemsets as vertices[1] Figure 9: Rules as vertices[1]

  10. 5.Parallel Coordinates Plot Figure 10: Parallel coordinate plot (reordered)[1]

  11. Parallel Coordinates Plot • To visualize multidimensional data. • X-axis -- the positions in a rule, i.e., first item, second item, etc. • Head of arrow -- points to the consequent item. • The width of the arrows -- support • The intensity of the color -- confidence.

  12. Visualizing AR in Text Mining • A visualization of item associations with support > 0.4% and confidence > 50%. Figure 11: A visualization of item associations)[2]

  13. Infovis application Framework • Prefuse: a toolkit for interactive information visualization • Provides theoretically-motivated abstractions for the design of a wide range of visualization applications, enabling programmers to string together desired components quickly to create and customize working visualizations[5] • E.g. racialgraphic • Ajax.org (Javascript) • AnyChart (Flash) • Axiis • Degrafa • ExtJs
