As a thinking tool, to visually organize information As a development tool, for working with graph data As a communication tool, for describing what is in the graph As an interactive tool, for exploring data relationships As a reporting tool, for summarizing business information As an analysis tool, for revealing critical trends, influences and discrepancies 6 Survey: How is graph visualization useful?

  9. 9. What is Neo4j Bloom? 9
  10. 10. Neo4j Bloom is "an interactive graph visualization environment" which focuses on creating a business view of the graph, for business users. Two main activities: 1. Defining a business view of the graph 2. Interacting with that business view

  12. 12. 13
  13. 13. Quick Start The first time that Bloom encounters a graph, it will offer a selection of currently defined "Perspectives" or to auto-generate a new one. Auto-generation is a good place to jump quickly into graph exploration.
  14. 14. Quick Start Use search to find: • expected values, like "Tom Hanks" • patterns, like "Movies" or "Persons in Movies" Interact by: • double-clicking a node to see details • right-click to bring up a context menu
  15. 15. • High fidelity • Scene navigation • Property views • NLP Search • Search suggestions • Saved phrase history • Graph editor • Schema Perspectives Neo4j Bloom 16 Communicate, discover, visualize, isolate and navigate
  16. 16. Neo4j Bloom User Interface 17 • Prompted Search • Property Browser & editor • Category icons and color scheme • Pan, Zoom & Select
  17. 17. Category List Acts as a legend for the Scene. Default Category: catches any Nodes which don't map to a Perspective Category Perspective Categories: defined by the current Perspective* Each Category shows: • selected count • in-scene count (visible somewhere) • category name • category color *see Perspective Drawer for details about defining Categories
  18. 18. Search Main way of interaction: • Graph Patterns • Lookups by attributes • Fulltext search • UI Actions
  19. 19. Context Menu Additional Functionality • Expand • Dismiss • Change selection • Path finding • Undo • UI Actions • Start Editing
  20. 20. Editing Code free editing • Add Nodes • Edit Labels • Edit Attributes • Connect Nodes • Limit to perspective
  21. 21. Graph Perspectives
  22. 22. Graph Perspective 23 Manage visibility and reduce clutter, revealing the right information to the right users. • Selective Property Visibilty • Selective Relationships • Defined Entity Patterns* Need-to-know Details • Departmental Views • Hide Personal Ident Info • Structural-only Dev view Rich Entities* • Truck with Packages • Person with Aliases • Blog Post with Comments • Component with Parts

  31. 31. Graph Search 45 Ask Bloom what you’re looking for using idiomatic phrases based on the graph structure and content. • Search Everywhere • Find Graph Patterns • Customize Search Phrases “Tom Hanks” “Tom Hanks Movies” “From Tom Hanks to Kevin Bacon”
  32. 32. Search Bar Four kinds of input: • Graph Pattern • Full-text Search • Search Phrase • Action Graph Pattern Full-text search Search Phrase Action
  33. 33. Search Bar: Graph Pattern Graph Pattern search accepts a relaxed pseudo-natural language grammar based on a dictionary drawn from Node Labels, Relationship Types and Property Keys. The terms are mapped to potential pattern matches which a user can select. Value-matches based on indexed properties can also be used to complete a Pattern. Graph Pattern
  34. 34. Search Bar: Full-text search When the Bloom full-text search plugin is available, that will be used to fulfill the search. Otherwise the search is restricted to looking up text in the available indexes. No indexes and no plugin? Full-text search will not work. Full-text search
  35. 35. Search Bar: Search Phrase Search Phrases are defined within the Perspective, allowing for highly customized domain-specific questions to be asked. • paired with a parameterized Cypher query • can call algos, or anything! • could mutate the graph (requires write access) (See How-to define a Search Phrase) Search Phrase
