#**GexfWalker** - *What happens after Gephi?*



- **author**: Alexis Jacomy, *alexis dot jacomy at gmail dot com*

- **project**: La Carte du Tendre du Web / The Web Tenderness Map



##I. Introduction



This open source web widget is developped as part of the **Web Tenderness Map project**. This project aims to represent the current tenderness map as a websites network. GexfWalker is diffused under the **MIT license**.



If many applications are already available to explore and visualize graphs (as Gephi, GUESS, Pajek, etc...), there is not a lot of ways to experience **on the Web** a **local** and **global** navigation of these graphs (the best examples I know are the noticeable [Moritz Stefaner's Relation Browser](http://moritz.stefaner.eu/projects/relation-browser/) and the really good [MindPlayer](http://thisislike.com/mindplayer) of [ThisIsLike.com](http://thisislike.com/) for the local view). This tool is particularly developped for the Gephi and GEXF users community. It is all about GEXF, and is supposed to work with **any graph spatialised from Gephi and exported as a GEXF file**.

##II. Functionalities



Currently, GexfWalker allows the user to:



- Explore the global layout of the graph (the global view)

- Explore the relations related the nodes (the local view)

- In local view:

  - Visualize the attributes of the current selected node

  - Click on a neighbour of the current selected node to select it

  - In case of too many neighbours and labels overlapping, choose the neighbour to select with a combo box (bottom left on the screen)

- In global view:

  - Click on a node to select it into the local view

  - Select a node in the bottom left combo box to pass to the local view

  - Zoom with the mouse wheel

  - Drag and drop the graph with the mouse

- And even more:

  - Meta data visualisation

  - Hypertext links automatically recognized in meta data and attributes

  - The SVG background of your choice (see use case at [OfNodesAndEdges.com](http://ofnodesandedges.com/display-geocoded-graphs-with-gexfwalker/))



##III. How to try it



You need first to have installed on your computer the Adobe Flash Player (if you can watch videos on YouTube, then it is already done). Then:



1. Download the last stable version in the [Downloads](http://github.com/jacomyal/GexfWalker/downloads) section of this GitHub homepage.

2. Open with your web browser the file **GexfWalker_sample/index.html**

3. Enjoy the exploration!



##IV. How to install it on your website



You need first to have a spatialised GEXF-formated graph from the open-source software [Gephi](http://www.gephi.org/) (see the tutorials [here](http://www.gephi.org/users)). Then:



1. Download the last stable version in the [Downloads](http://github.com/jacomyal/GexfWalker/downloads) section of this GitHub homepage.

2. Host somewhere on your website the file **GexfWalker_sample/GexfWalker.swf** and **your GEXF file**.

3. Replace in **GexfWalker_sample/index.html** on lines 73 and 77 **"./GexfWalker.swf"** by the relative path of this file on your server.

4. Replace in **GexfWalker_sample/index.html** on lines 73 and 77 **"./sample.gexf"** by the relative path of your gexf file on your server. 

5. Copy/paste on your web page the new HTML code where you want to display your graph.



Finally, your webpage will allow users to explore the graph of your choice.



**You can also change some other display settings**, for example by replacing the values of **width** and **height** in lines 8 and 77 of the HTML code.
