This is a plugin for Gephi, a graph visualization and manipulation software package.

With this plugin, nodes can be given a attribute (column) called ‘image’ that contained a image file name. those images are then loaded from a given path (provided by the Preview Settings). The images appear in the preview window, and can be exported with the SVG/PDF/PNG option. Please note that this is an early version of the plugin, and still contains many bugs. Please feel free to supply any feedback you may have. Please note that we have very limited resources and can not guarantee any future updates or changes. If you wish to help, let us know.

This plugin was developed by the Yale Computer Graphics Group. We released it in the hopes it will be useful, but make no guarantees that it will work (see the GPL for a full disclaimer).

Feel free to create an issue on GitHub if you need to contact us.

This layout uses an isometric perspective to visualize networks. I.e. it generates 3D coordinates for all network nodes (x,y,z).
Thus, is a method for the visual representation of three-dimensional nodes in two dimensions.
It can be used to split a network into distinct Z-Layers (e.g. to better visualize high-performers and/or low-performers, or communities after using modularity algorithms).
Besides, computed Z-layers can be used in Gephi ranking and/or partition procedures.
To use 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 IsometricLayout 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).

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” Dipl. 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.

Reads an attribute for nodes containing a RGB or #hex value. Colors nodes accordingly.

When is it useful?

This plugin gives you full control on the color of your nodes in Gephi. Define the color for each node as an attribute, that’s it!

Quick instructions

1. Your nodes should have an attribute containing “color” in its name. For example, something like “myColor” would work.
2. The value of this attribute for each node can be RGB (example: “255,0,0″ -> for the red color) or hexadecimal (example: “#00FF00″ for bright green).
3. Click on this pic to enlarge the illustration:

illustration

4. After installing the plugin, restart Gephi.
5. A new icon in the form of a color wheel appears on the left of the graph window (below existing icons). Click on the illustration below to see where the icon is exactly located:

illustration2

6. Click on the icon, your nodes will be colored according to their color values!

Author of the plugin

Clement Levallois. The original idea was suggested by Frank van der Most.

Convert Excel spreadsheets and csv files into networks

This plugin helps transform your Excel files (or csv files) into a network, directly imported into Gephi. You can choose which entities, and which relations, form the network.

1. Quick how-to

- Install the plugin in Gephi (File -> Tools -> Plugins -> Available).
- Restart Gephi

In the Gephi menu, select File -> Import Spigot.
- Select “Data importer”
- Get your Excel file ready!
- Follow the steps of the wizard.

2. To go further…

The plugin gives you the possibility to create network of two types of entities. Let’s say that your Excel file looks like:

Author Book Year Sales of the book
David My life 1972 350 copies
Mary My story 1968 400 copies

In the wizard you’ll get to a window where you’ll select “Author” and “Book” as the two types of entities you want to connect:

(click to enlarge)

bipartite

And the result in Gephi will be:

network bipartite

This looks fantastic, but in practice this type of networks gets quickly messy – lots of connections between both types of agents, making it hard to disentangle and to visualize.

 

-> For this reason, I’d suggest to also try the plugin on this type of files:

Author Book Year Sales of the book Literary agent
David My life 1972 350 copies Philip
Mary My story 1968  400 copies Philip

 

Here, by selecting a network made of ‘Authors’ and ‘Literary Agent’ in the plugin, the resulting network will be much more interesting (because it is made of one type of agents: persons).

So in the plugin you select (click to enlarge):

tttt

 

And this leads to something more meaningful, in my opinion at least:

 

network

Enjoy!

Version 1.3 (March 2014). Bug fix: same names in different columns are now treated correctly. Bug report / analysis by Wouters A.H. Spekkink.

Function of the plugin

Use this plugin to insert maps of countries and world regions in Gephi.

 

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?

- 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.
