9. What is Neo4j Bloom?
9

11. 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. Visual Tour

14. 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.

15. 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

16. • High fidelity
• Scene navigation
• Property views
• NLP Search
• Search suggestions
• Saved phrase history
• Graph editor
• Schema Perspectives

Communicate, discover, visualize, isolate and navigate

17. Neo4j Bloom User Interface
17
• Prompted Search
• Property Browser &
editor
• Category icons and
color scheme
• Pan, Zoom & Select

18. 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

19. Search
Main way of interaction:
• Graph Patterns
• Lookups by attributes
• Fulltext search
• UI Actions

20. Context Menu
Additional Functionality
• Expand
• Dismiss
• Change selection
• Path finding
• Undo
• UI Actions
• Start Editing

21. Editing
Code free editing
• Add Nodes
• Edit Labels
• Edit Attributes
• Connect Nodes
• Limit to perspective

32. 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”

33. Search Bar
Four kinds of input:
• Graph Pattern
• Full-text Search
• Search Phrase
• Action
Graph Pattern
Full-text search

Action

34. 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

35. 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

36. 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)
