7.3 Using the Graph Visualization Application

Depending on the PGQL driver selected at the time of logging in, the Graph Visualization application is either connected to the database or to the graph server (PGX).

In both cases, the principal points of entry for the Graph Visualization application are the query editor and the graph list which displays the list of graphs existing either in the graph server (PGX) or in the database.

The following sections explain the application user interface and running PGQL queries for visualization in detail:

• Visualizing PGQL Queries on Graphs Loaded Into the Graph Server (PGX)
  To run PGQL queries on a graph loaded into the graph server (PGX), you must login to the Graph Visualization application by selecting the Graph Server advanced option in the login screen.
• Visualizing PGQL Queries on Graphs in the Database
  To run PGQL query on graphs in the database, you must login to the Graph Visualization application by selecting the Database advanced option in the login screen.
• Graph Visualization Modes
  The buttons on the right let you switch between two modes: Graph Manipulation and Zoom/Move.
• Graph Visualization Settings
  You can click the Settings gear icon to display the Graph Visualization settings window.
• Using the Geographical Layout
  The Graph Visualization application offers a choice of layouts for rendering graphs. One of them is the Geographical layout that will show the graph (vertices and edges) on a global map.
• Using Live Search
  Live Search lets you to search the displayed graph and add live fuzzy search score to each item, so you can create a Highlight which visually shows the results of the search in the graph immediately.
• Using URL Parameters to Control the Graph Visualization Application
  You can provide the Graph Visualization application input data through URL parameters instead of using the form fields of the user interface.
