10. I’m not a designer… - But learning basic principles of design and data visualization is not so hard - Creating 10/10 visualization is difﬁcult, but 8/10 is the goal for us - Let’s avoid pitfalls!

11. What is BAD Visualization? - Lack of story - What’s the point? - Hard to understand - Too many or too few visual mappings - Ugly

12. Story (or Goal) - Example: - I want to show the changing levels of gene expression for three time points - Assign gene expression proﬁle to the primary visual property in your visualization

14. “Cool” does not always mean “Eﬀective” - This is what I’ve learned from my past experiences…

15. Case Study: 3D Visualization - Background: - In late 90’s, 3D graphics card was cheap enough for entry-level workstations - Many researchers made tons of 3D graphics applications for data visualization

16. 3D Network View by igraph

17. Carpendale et al. 96. Distortion Viewing Techniques for 3-D Data

18. What is the Advantage?

19. …And My Mistakes

20. Experimental 3D renderer for Cytoscape

21. Technology Oriented, Lack of Story!

22. What was the problem? … It would be more accurate to say that visual space has 2.05 dimensions.

23. Lessons Learned… - Introduce additional dimension / complexity to the visualization only when it is necessary - Animation, 3D, charts on nodes, etc. - Use minimal set of visual channels to make the visualization understandable - Deﬁne story (or goal) before creating actual visualization - Understand human perception

24. Goal of Scientiﬁc Data Visualization - Help scientists to understand their data sets - Tell a STORY

25. - Just follow some simple principles - Info-Graphics != Data Visualization - Art/Design : Science - Infographics 8:2 - Scientiﬁc Visualization 1:9 You Don’t Have to be a Professional Designer

26. What is Good Visualization? http://www.visualcomplexity.com/vc/

27. - One of the unfortunate trends in data-driven life sciences is that they increasingly use programmers to abstract data so that mundane information looks visually appealing - this is motivated by the desire to appear on the cover of the glossy life sciences journals. - Comment from Wired Magazine article “Circle of Life: The Beautiful New Way to Visualize Biological Data” http://www.wired.com/wiredscience/2013/11/wired-data-life-martin-krzywinski/

28. An Extreme Example (I’m not saying this is bad, but…)

29. http://youtu.be/WTHtYZcH6fk

30. Don’t be Too Cool! - Cool visualizations are sometime useless for scientists - But still good for journal cover page… - Balance coolness and effectiveness - Think about audience (or users if it is interactive)

31. Visualizing Heterogeneous Data In a Diagram is HARD - Visualization itself is a research area - You should learn about commonly used techniques and principles from experts

32. Human Interactome data from BioGRID visualized by Cytoscape

33. Large Scale Visualizations are Pointless in Many Cases

34. Good Large-Scale Visualizations

35. Ultimately, you want…

37. But this is still useful

38. Costanzo et al.

39. Targeting the Audience - Even meaningless (but cool) visualization is useful as a eye-catcher or journal cover page - When you need ﬁgures for your publication, minimize the noise in your visualization and keep it simple

48. In Cytoscape… 1. Position: Node Position 2. Length: Edge Length 3. Area: Node Size, Edge Width 4. Color: Node/Edge/Label Color 5. Density: Node/Edge/Label Transparency

49. 1. Position

50. Power of Layout

53. Layouts - Some cases, manual editing is necessary - Start from tweaked automatic layout, and then use techniques discussed later

54. Group Similar Nodes

55. Cytoscape Function for This - Apply layout to selected nodes only

56. Use Case - Show group of nodes in same cellular location - Same functional groups

57. Tweak Layout Parameters

58. - Layout - Settings to tweak parameters Cytoscape Function for This

59. Stacking & Grouping

60. - Manual Layout Cytoscape Function for This

61. 2. Length

62. In Cytoscape - Edge Length - Can be used for the similarity of the connected nodes - Long = less related - Short = closely related

63. Scaling

64. 3. Area

65. In Cytoscape - Node Size / Edge Width - Two strongest visual channels for mapping your data - Use these two for your important data - Automatic layout algorithms can be applied only to selected group of nodes

66. Edge Weight to Width

69. 4. Color

70. In Cytoscape - Node/Edge/Label Color - Less accurate, but still useful especially when you map to continuous values - Automatic layout algorithms can be applied only to selected group of nodes

71. Expression Values To Node Colors

72. Common Pitfall: Use Too Many Colors - Simply awful - Hard to understand - Doesn’t tell anything!

73. Colors for Categorical Data - Again, limitation of our perception — Use up to 6~7 Colors - Preferably, 3-4 - Less is better!

74. 5. Density

77. Other Tips

78. Avoid Data Overload - Mapping too many attributes makes your visualization awful! - It is hard to see the overall trend if too many channels are used in a image

80. Move Label Position

81. # of Visual Properties is Limited - Use them effectively - Don’t use too much in the same view

82. STMN1 SMARCD3 SMARCA4 SMARCD3 TUBB HTT OPTN PPARG PSMD1 MAP4K4 ATP6V1C1 Start from Scratch - If you are not sure you need the decoration or not, remove it - Example: Node border, edge arrow - Even labels are not always required!

83. “Great Artists Steal…”

84. Summary - Learn basic principles of data visualization - Write a story before creating visualization - What do you want to tell by the diagram?

85. External Tools

86. External Tools - Biological data analysis is not simple! - There is no such thing: one-size-ﬁts-all - Need to understand de-facto standard tools to save your time

87. Network Data Analysis Analysis Graph Analysis NetworkX igraph Cytoscape Python Pandas NumPy SciPy Excel Visualization Desktop Gephi Cytoscape matplotlib Web Cytoscape.js sigma.js d3 NDV3 d3.chart Google Charts Data Storage Graph Neo4j GraphX Document MongoDB Relational MySQL IPython 3rd Party Apps NetworkAnalyzer

88. Network Data Ana Analysis Graph Analysis NetworkX igraph Cytoscape Python Pandas NumPy SciPy Excel Visua IPython 3rd Party Apps NetworkAnalyzer

89. Data Analysis Tools Analysis VisualizationData Preparation

90. Data Analysis Tools - Languages / Platforms - R + Bioconductor - Python + Pandas - MATLAB - Excel - Graph analysis library - igraph - NetworkX

91. Data Visualization Tools - Data visualization on web browsers are getting more and more important… - Cytoscape.js - sigma.js - D3.js

92. - Need more analysis functions - Cytoscape can perform network analysis interactively, but does not have complete suite of network data analysis tools - These days, cutting-edge methods and algorithms are implemented in Python - Easy to implement, yet fast (because of NumPy/SciPy) - Batch analysis - Visualize in web browsers Why Multiple Tools?

93. - Avoid reinventing the wheel - igraph and NetworkX have a lots of network analysis functions. Why should we repeat it again? - Collaboration rather than competition - General policy for our project Why Multiple Tools?

94. Glue for Applications - There are two ways to use external tools with Cytoscape - Common ﬁle formats - RESTful API for programatic access (Ongoing)

95. - Use popular, standard, widely-used data formats ! - GraphML (Recommended) - CSV/TSV - Not a format, but easy to process in scripting languages and spreadsheet File-Base Data Exchange

96. Realistic Example - Prepare data in Python - Load data from Bioconductor - Calculate network statistics with igraph - Export networks and tables in GraphML format  - Visualize it in Cytoscape

97. Realistic Example - Prepare data in Python - Load data from Bioconductor - Calculate network statistics with igraph - Export networks and tables in GraphML format  - Visualize it in Cytoscape

98. Coming Soon… - Programatic access to Cytoscape objects and functions via REST - /networks/ID/nodes/NODEID - /apply/layout?network=ID - We need your opinion!

99. Communication Bus NDEx (DB) Browser Cytoscape Desktop

100. Web and Cytoscape

101. - Prepare/integrate/analyze data with R/Python or traditional desktop applications - Visualize & publish it as web apps Trends in Data Visualization

102. Web!

103. Into The Web… - Cytoscape is a Java desktop application - Need glue modules to use existing Cytoscape features from web browsers

104. New in Cytoscape 3.1.0: Export Networks and Visual Styles to Cytoscape.js Format JS Integration to Cytoscape

105. Cytoscape.js is NOT - Complete web application - Compatible with Cytoscape Apps - Replacement for Cytoscape

106. Export to Cytoscape.js Demo
