Adjacency Graph Builder Demo
This demo interactively builds and modifies a graph from JSON business data using
See the the Developer's Guide section on the
for an in-depth explanation of the relevant concepts.
The demo allows to define nodes sources and edges bindings using the schema graph
component on the right. The schema nodes represent nodes sources. The schema edges
represent the edge bindings between the nodes sources. The edge arrows indicate the type
of the edge. An arrow pointing away from a node indicates outgoing edges to successor
nodes. An arrow pointing towards a node indicates incoming edges from predecessor nodes.
Things to Try
- Select a sample in the combo box and inspect its data and sources on the right.
Double click on a node in the schema graph and edit the schema nodes' business data.
Octagonal schema nodes represent nodes sources that provide business data for the result
Circular schema nodes represent nodes sources without own data, that receive data via
the edge bindings.
- The schema graph edges and labels define the result graph edge bindings.
- Click on an edge or its label to edit the edge binding.
- Right-click on a schema edge to invert its neighbor type via its context menu.
Enter an empty edge label content to remove the edge and thus the result graph edge
- Click into the empty space of the schema graph to create a new schema graph node.
Drag from an existing schema graph node and drop on the empty space to create a new node
connected to it.
- Connect existing schema graph nodes by dragging and dropping between them.
- Build a graph from your own data and bindings.
Note: This demo shows only parts of the AdjacencyGraphBuilder API.
In addition to the functionality available in this demo, the AdjacencyGraphBuilder allows
to reference nodes by their ids and edges may be defined by their own edge data items.
Since this demo evaluates the complete data source texts every time a source is edited,
Update Graph works as expected only for node data items of primitive type or if
the node id binding resolves to primitive ids. Note that this restriction applies only to
the demo, not the class AdjacencyGraphBuilder.
