Manipulating the graph: Layouts

Visualization controls

On the Workspace, various controls are available on the right-bottom of the screen:

  • The shortcuts button: , give access to a list of shortcuts to explore and interact with the graph.
  • The Locate button centers the graph on the screen.
  • The Zoom In/Zoom Out button is to zoom in or zoom out on our graph.
  • The Layout button give us various options to organize our graph.

A click on the layout button will apply the current layout, which is a fast force-directed layout by default. Two categories of layouts are available: force-directed, and hierarchical. They come with pre-defined flavors:

Force-directed layout

Such layouts position nodes according to their connections: connected nodes are usually closed to each others, while disconnected nodes are usually pushed further.

Best Mode: Takes the longest time to compute new node positions but provides better results than the Fast Mode.

Fast Mode (default): Quickly finds new node positions but some overlapping nodes may exist.

Random Mode: Node positions are randomized before computing new node positions.

Hierarchical layout

Such layouts organize nodes in different layers automatically by aligning nodes of each layer either vertically or horizontally. The root nodes are automatically found.

Top to bottom Mode: Will position root nodes at the top of the screen.

Left to Right Mode: Will position root nodes at the left side of the screen.

Bottom to top Mode: Will position root nodes at the bottom of the screen.

Right to left Mode: Will position root nodes at the right side of the screen.
