D3 graph service module provides a graph visualization of the topic map in Wandora. D3 graph service module is part of Wandora's embedded HTTP server. It is based on open source Javascript visualization library D3.js. Service module's alias is d3graph and access URL
http://127.0.0.1:8898/d3graph
Graph visualization provided by the D3 graph service module contains only binary associations and the number of viewed topics is limited to 1000 by default. Wandora user can override this limitation with an HTTP parameter n. For example, accessing URL
http://127.0.0.1:8898/d3graph?n=9999
sets the maximum number of viewed topics to 9999. It depends on user's computing resources whether or not the created visualization is usable with 9999 nodes. Screen capture below views a d3graph visualization generated out of Wandora's default topic map. User can zoom in and out the graph visualization using mouse wheel. Dragging a node moves it. Dragging background moves whole graph. Mouse over on a node fades out other graph nodes.
Next screen capture views a d3graph visualization after a hexagonal tiling generator of depth 5.
