Graph

The graph report will render all returned nodes, relationships and paths in a force-directed graph layout. This includes collections (lists) of these objects.

The library react-force-graph is used to create the visualizations. Depending on your browser, the visualization should be able to handle drawing 1000-3000 nodes/relationships with custom styling options.

The graph layout contains an extensive set of features, including:

  • Drag and drop nodes.

  • Custom node/relationship styling.

  • Tooltips/inspect window on nodes/relationships.

Examples

Basic Graph

MATCH (p:Person)-[a:ACTED_IN]->(m:Movie)
WHERE m.title = 'The Matrix'
RETURN p, a, m
Basic Graph

Virtual Graph (apoc is required)

MATCH (p:Person)-[:ACTED_IN]->(m:Movie)<-[:ACTED_IN]-(p2:Person)
WHERE m.title = "The Matrix"
RETURN p, p2, apoc.create.vRelationship(p, "KNOWS", {}, p2)
Virtual Graph

Advanced Settings

Name Type Default Value Description

Node Color Scheme

List

neodash

The color scheme to use for the node labels. Colors are assigned automatically (consequitevely) to the different labels returned by the Cypher query.

Node Label Color

Text

black

The color of the labels drawn on the nodes.

Node Label Font Size

Number

3.5

Size of the labels drawn on the nodes.

Node Size

Number

2

Default size of a node in the graph visualization. This size is applied if no custom size styling is defined and no Rule-Based styling is active.

Node Size Property

Text

size

Optionally, the name of the node property to map to the node size. This lets you define sizes on a node-specific level, if you have a property that directly maps to the numeric size value.

Node Color Property

Text

color

Optionally, the name of the node property to map to the node color. This lets you define colors on a node-specific level, if you have a property that directly maps to the HTML color value.

Relationship Color

Text

#a0a0a0

The color used for drawing the relationship arrows in the visualization.

Relationship Width

Text

1

The (default) width of the relationship arrows in the visualization.

Relationship Label Color

Text

#a0a0a0

The color of the labels (relationship type) drawn next to the relationship arrows.

Relationship Label Font Size

Text

2.75

The font size of the labels (relationship type) drawn next to the relationship arrows.

Relationship Color Property

Text

color

Optionally, the name of the relationship property to map to the arrow color. This lets you define colors on a relationship-specific level, if you have a property that directly maps to the HTML color value.

Relationship Width Property

Text

width

Optionally, the name of the relationship property to map to the arrow width. This lets you define widths on a relationship-specific level, if you have a property that directly maps to the width value.

Animated Particles on Relationships

on/off

off

If enabled, draw relationships with animated particles on them, moving in the direction of the relationship.

Background Color

Text

#fafafa

The background color of the visualization.

Layout (experimental)

List

force-directed

Use this to switch from the main (force-directed) layout to one of the two experimental layouts (tree/radial). For the experimental layouts, make sure your graph is a DAG (directed acyclic graph).

Show pop-up on Hover

on/off

on

if enabled, shows a pop-up when a user hovers over one of the nodes/relationships in the visualization. The pop-up contains the label and properties of the node/relationship.

Show properties on Click

on/off

on

if enabled, opens up a window when a user clicks on one of the nodes/relationships in the visualization. The window contains the label and properties of the node/relationship.

Fix node positions after drag

on/off

on

If enabled, locks in (freezes) the node positions after a user drags them.

Drilldown Link

Text (URL)

(no value)

Specifying a URL here will display a floating button on the top right of the visualization. This button can be used to drilldown into a different tool (e.g. Bloom) so that the graph can be explored further. Dynamic Dashboard Parameters (e.g. $neodash_person_name) can be used in these links as well.

Hide Selections

on/off

off

If enabled, hides the property selector (footer of the visualization).

Auto-run query

on/off

on

when activated automatically runs the query when the report is displayed. When set to `off', the query is displayed and will need to be executed manually.

Rule-Based Styling

Using the Rule-Based Styling menu, the following style rules can be applied to the graph:

  • The background color of a node.

  • The label color of a node.
