The layout takes the coordinates of a Multidimensional Scaling (MDS) configuration as inputs and uses these coordinates to layout the nodes of a graph. MDS is sometimes used in Social Network Analysis to create layouts that reflect some type of distance between the nodes. This distance can be based on the length of paths between the nodes, but it can also be based on (dis)similarities in attributes of nodes.

A separate plugin is available for MDS analysis (MDS Statistics) from the Gephi Marketplace. It is also possible to perform the MDS analysis with external software (e.g. R or SPSS). In the latter case the coordinates of the MDS configuration have to be added to the nodes list manually.

If you have the results of an MDS analysis, add the coordinates as variables to your nodes list. When importing the nodes list, make sure that you import the nodes as ‘doubles.’ Otherwise the layout plugin won’t be able to read the coordinates and use them for the layout.

Description

The event graph layout plugin was written to allow for the easy creation of event graphs. In an event graph the nodes represent events and the edges/arcs represent relationships between the events (e.g. causality). The layout plugin places the events in a user-specified order on the x-axis. If vertical force is activated, the plugin will push unconnected groups of events away from each other on the y-axis, and keep connected nodes together.

How to use

To use this plugin you need to add a numerical variable (integer, float or double) to your nodes that gives them a rank order. This rank order will be used to determine the position of the nodes on the x-axis. Typically, this order variable will indicate the order of events (represented by the nodes) in time. The order scale can be used to scale up or scale down the distances between the nodes on the x-axis.

In its default setting the plugin will only lay out the nodes on the x-axis. If vertical force is activated the plugin will also lay out the nodes on the y-axis, based primarily on their degree of interconnectedness. Thus, groups of nodes that are highly interconnected tend to stay close to each other, and nodes that are not highly interconnected tend to drift away from each other. The vertical force can be used to increase or decrease the distance between the nodes on the y-axis.

Hints

  • For larger event graphs it may be helpful to increase the jitter tolerance somewhat if the vertical layout moves too slow.
  • If you want to move the nodes on the y-axis with your mouse, but want to make sure that they keep their position on the x-axis, then run the plugin without vertical force activated

Each node is given an x, y, and z. While normally this Z is not seen in the 2D Gephi view, it is used by other 3D algorithms (like Force Atlas 3D) and can be exported.

E.g. after using layouts such as: Yifan Hu, Fruchterman Reingold, Force Atlas, Circular, Layered, OpenOrd, etc.

Computed Z-Layers can be used in Gephi ranking and/or partition procedures. To use this plugin it is quite simple: network nodes should have an attribute containing “[z]” in its name. E.g. something like “Degree [z]” or “YourNodeColumn[z]“.

The Network Splitter 3D will compute and segment z-Levels regarding your “[z]” column values (with any ranges). If your network don’t have a “[z]” column, no problem, all nodes will be placed in Z-Layer 0 (Zero).

Another usefull feature:
You can use this plugin to rotate your graph over the X-Axis.

This plugin is developed as part of the “KSD research group”, where the German Research Center for Artificial Intelligence GmbH (DFKI), University of Kaiserslautern and the Technische Universität München (TUM) take part.

“During the design process architects and students often study the plans of buildings that have already been built or designed. Such information is available conventionally as a form of collective memory in architectural monographs and journals as well on the internet. […]
Our goal [of the KSD research group] is to support the early stages of the design process using information technology in order to find similar built architectural solutions as a source of inspiration, an explicit solution, or a means to better understand current or design problems. […]
To formalize architectural situations digitally we propose to create semantic fingerprints of buildings, to be used to identify a building as we use actual fingerprints to identify of individuals. In order to map the spatial structure of architectural situations, graph-based approaches are being investigated to mathematically represent fingerprints for information such as space and their connections, alignment, orientation or urban integration.”

http://ksd.ai.ar.tum.de/category/aim/

This plugin supports the creation of those fingerprints as graphs. Furthermore, it adds a spatial dimension to Gephi by displaying the original ground plans. Additionally, some tools were added to evaluate the created fingerprints by colorizing the nodes / edges and setting its weight.

This work was supported, lead and made possible by the leader of the “KSD research group” Dr.-Ing. Architekt Christoph Langenhan from the Technische Universität München. It has been implemented by Thomas Stocker as Interdisciplinary project (IDP) between the Chair for Architectural Informatics from Prof. Dr.-Ing. Frank Petzold and the informatics department.

Function of the plugin

Use this plugin to insert maps of countries and world regions in Gephi. Now also includes country sub-regions: states and territories of Australia. You can also control the thickness of the line with the “Weight” parameter.

 

Quick instructions

- Install the plugin, open a new Project, go to the layout tab and select the layout “Map Of Countries”.

- Click on “Run” to load the map of the world.

 

All features explained

Besides showing the map of the world, you can show single countries, subregions (parts of continents), and regions (continents).
Please refer to the original data source for the definitions of borders: http://thematicmapping.org/downloads/world_borders.php.

 

1) To load just the map of a single country (example: Laos):
-> “No subregion” must be selected in the subregion dropdown menu
-> “No region” must be selected in the region dropdown menu
-> Select “Lao People’s Democratic Republic” in the country menu, and click “run”.

2) To load just the map of a subregion (example of a subregion: South-Eastern Asia):

-> “World” must be selected in the countries dropdown menu
-> “No region” must be selected in the region dropdown menu
-> Select “South-Eastern Asia” in the subregion menu, and click “run”.

3) To load just the map of a region (example of a region: Asia):
-> “World” must be selected in the countries dropdown menu
-> “No subregion” must be selected in the subregion dropdown menu
-> Select “Asia” in the region menu, and click “run”.

 

These maps and your network: how do they interact?

Note: if your map and your network are slightly off mark, run the “Geolayout” plugin once to get them properly aligned.

- You can have a map and your network shown in the same project – that’s what this plugin is for!

- Loading a new map will erase the one previously displayed, but will leave your network intact.

- If you want to delete / modify the map manually, go to the data laboratory and look for nodes that have a label “background_map_node”

- What if you apply a layout (like Force Atlas 2) to your network? Your network will move, but the map is “fixed” so it will stay as it is.

- What if you apply the Geolayout plugin to your network? To do that you need your latitude attribute to be called “lat” and the longitude called “lng” for the nodes of your network. If you have that, your network will be nicely placed over the maps.

Release History

Sept. 24, 2013: 1.0, first release

Oct 19, 2014: 1.1, removed labels from background nodes because they were just an inconvenience.

Jan 5, 2015: 1.2, solved a null pointer exception.

May 13, 2015: added Australian states / territories and built support to easily add more regions from other countries.

Aug 05, 2015: 1.4, added a new feature: “Weight” allows to control the thickness of the lines of the borders
