Adding in 3D graph visualization as an advanced visualization (#737)

* Multiple relationships between nodes in 3D graph & self-loops

* Refactoring graph code

* Renamed files for graph visualization interface

* Refactored 2D/3D graph to share a common base

* Enabled report actions

* Finalized 3D graph code

* Added docs for 3D graph

* Fixed non-https placeholder for advanced setting

* Actions/rule-based styling for 3d graph

 To use advanced visualizations, enable them in the **Extensions Window**. This makes them selectable inside reports, as well as add examples to the Example window.
 
 The following visualizations are part of this extension:
-
+- A link:../../reports/graph3d[3D Graph] to visualize a graph in three dimensions.
 - A link:../../reports/sankey[Sankey Chart] to visualize flows.
 - Three charts to plot hierarchical data (link:../../reports/sunburst[Sunburst], link:../../reports/circle-packing[Circle Packing], link:../../reports/treemap[Treemap])
 - A link:../../reports/gauge-chart[Gauge Chart] to show percentages.

+|===
+|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.
+
+|Arrow head size |Number |3 |Use this to set the length of the arrow head, size is adjusted automatically.
+If 0, no arrow will be drawn.
+
+|Background Color |Text |#fafafa |The background color of the
+visualization.
+
+|Layout (experimental) |List |force-directed |tree-top-down |tree-bottom-up |tree-left-right |tree-right-left |radial | Use this to switch from
+the main (force-directed) layout to one of the experimental layouts
+(tree, radial). For the experimental layouts, make sure
+your graph is a DAG (directed acyclic graph).
+
+| Graph Depth Separation | Number | 30 | Specify the level distance for the tree layout. 
+This setting controls the separation between different levels in the tree hierarchy. Adjusting this value impacts the overall spacing of the tree layout in your graph visualization.
+
+|Enable graph exploration |on/off |on |Enables basic exploration functionality for the graph. Exploration can be done by right clicking on a node, and choosing 'Expand' to choose a type to traverse. Data is retrieved real-time and not cached in the visualization.
+
+|Enable graph editing |on/off |off |Enables editing of nodes and relationships in the graph from the right-click context menu. In addition, lets users create new relationships with existing types/property keys as present in the database.
+
+|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.
+
+|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).
+
+|Override no data message |Text |Query returned no data. |Override the message displayed to the user when their query returns no data.
+
+|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.
+|Report Description |markdown text | | When specified, adds another button the report header that opens a pop-up. This pop-up contains the rendered markdown from this setting.

+
+== Rule-Based Styling
+
+Using the link:../#_rule_based_styling[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.
