什麼是一&nbsp.gexf&nbsp文件？
所述擴展用於在被寫入GEXF格式的文件。此格式包括結構，邊緣和曲線圖，這就是為什麼這些的所有屬性文件稱為圖形文件。這種格式主要用於由參與圖形項目誰的人。該文件格式允許創建結構的層次結構，這是在表示簇重要的。格式很容易讓用戶做他們的工作，因為動態的支持和層次結構的任務是不容易的。 文件通常保存在純文本，這擴展用於描述包含圖形數據和可視化文件。這些圖中的數據可以從一個應用程序到另一個，因為交換 。各種操作系統可以用來打開文件，它僅僅需要適當的應用，如Gephi和gexf4j。如果這些程序在計算機上都沒有找到， 文件定影液會做。文件固定器通常將文件轉換成一些在計算機可用的和相關應用可以打開的格式。
如何打開&.gexf&文件？
推出&.gexf&文件，或者你的電腦上的任何其他文件，雙擊它。如果你的文件關聯的設置是否正確，這意味著應用程序來打開你的&.gexf&文件將其打開。這是可能的，你可能需要下載或購買正確的應用程序。這也有可能是你有正確的應用程序在PC上，但&.gexf&文件還沒有與它相關聯。在這種情況下，當您嘗試打開一個&.gexf&文件，你可以告訴Windows的應用程序是正確的該文件。從這時起，打開&.gexf&文件將打開正確的應用程序。

Gephi features an open graph viz platform providing interactive exploration and visualization program for all kinds of complex systems and networks, hierarchical and dynamic graphs. It is an open source and free software that operates on Windows, Mac and Linux systems. It is a tool for exploring and understanding graphs [mixed, directed, undirected].
It explores data by real time network manipulation and intuition-oriented analysis. It performs link analysis by revelation of underlying structures of relationships between objects particularly in scale-free networks. It does social network analysis by creating social data connectors between small-world networks and community organizations. It analyzes biological data patterns for its biological network analysis. It creates posters of high-quality printed maps for science promotion. Gephi is a data workshop that lets you interact with the representation by manipulating the shapes, colors and structures to discover its hidden properties. It aims to help data analysts to formulate hypothesis, discover patterns intuitively, isolate faults or structures singularities while searching data. It complements traditional statistics as Visual Analytics by visualization through interactive interfaces is recognized to facilitate reasoning. You can profit from its fast graph visualization powered by established OpenGL engine for pattern discovery in large graphs. It provides an efficient and interactive network exploration with up to 1,000,000 edges and 50,000 nodes. Use dynamic filter to visualize and manipulate your graphs. Gephi provides the latest layout algorithms that give shape to your graphs. You can choose your layout settings [such as force-based algorithms and graph coarsening for multi-level algorithms] from the Layout palette while working for increased user feedback and experience. The statistics and metrics frameworks provides the most common metrics for scale-free networks and SNA [social network analysis] with features such as random generators, community detection [modularity], diameter, betweenness, closeness, clustering coefficient, PageRank, average shortest path and HITS. Gephi features DNA [dynamic network analysis] by filtering dynamic structures such as social networks in a timeline. You can perform graph streaming, and import temporal graph as GEXF file. Create cartography by using partition data and ranking to make your network presentation meaningful along with customized colors, labels and sizes. The vectoral preview module lets you aesthetically improve your representation before converting it to PDF or SVG format. Use data attributes and built-in clustering algorithms to create multi-level graphs such as hierarchical and clustering graphs. Filer your network and build new networks from your filtering results. Perform complex filter queries without scripting, and save
your favorite queries. Use Data Table to view and edit data. Organize your work and save your sessions as .gephi
project files. The architecture is modular and functionalities can be added. New features like Layouts, Metrics and Filters can be packaged in plug-ins and shared. It has Netbeans platform and API for extendable features. Native file formats are GML, NET [Pajek], GDF[GUESS], GraphML [NodeXL], GEXF, etc.

Gephi for MAC
Gephi is a visualization software for understanding and exploring graphs for your data analysis and research. Gephi 0.8.1beta is the latest stable version with new features including global and local scale ranking, new timeline with custom bounds settings, animation, embedded sparkline and date ticks, self-loop filter and modularity [community detection] for added edge weight support and resolution setting. It has better preview performance when hiding the edges. Gephi is a cross-platform software developed in Java. It requires Java 6 and later. Minimum hardware requirements are 128MB RAM, 500 MHz CPU, OpenGL 1.2, compatible graphic card for Gephi’s 3D OpenGL engine. Java 1.6 is available only on 64bit Intel Macs.
Java 6 can be installed on Mac OS X Leopard. Soylatte/OpenJDK is not supported on Mac OS.
要小心，不要重命名擴展&nbsp.gexf&nbsp文件，或任何其他文件。這不會更改文件類型。只有特殊的轉換軟件可以從一個文件類型更改一個文件到另一個。
什麼是文件擴展名？
文件擴展名是一組三個或四個字符在文件名的末尾，在這種情況下，&nbsp.gexf.&nbsp文件擴展名告訴你它是什麼類型的文件，並告訴Windows哪些程序可以打開它。窗戶經常關聯一個默認程序的每個文件的擴展名，這樣，當你雙擊該文件，程序會自動啟動。當該程序不再是您的PC上，有時可以得到一個錯誤，當您試圖打開相關的文件。

It supports attributes for nodes and edges, hierarchical graphs and benefits from a flexible architecture. Gephi supports a limited set of this format (no sub-graphs and hyperedges). This format is supported by , ,
File structure
The file content is wrapped into a graphml element. Then attributes columns (i.e. titles) are defined in key elements and finally the network in the graph markup.
Basic options can be set to set the graph element:
&graph edgedefault="directed"&
&graph edgedefault="undirected"&
Attributes definition
Each attribute title is defined in a key element with an identifier, a name, a title, edge or node, and the type of data. The supported data types:
Inside the markup, a default element can set the default value for the attribute. Below is an example of definition of two attributres, one for nodes and one for edges.
&key id="d0" for="node" attr.name="color" attr.type="string"&
&default&yellow&/default&
&key id="d1" for="edge" attr.name="weight" attr.type="double"/&
Custom data can be added by other software. The example under represents graphical representations (i.e. shapes), but it is not supported by Gephi at all. Verify files namespace to ensure compatibility.
&node id="n2"&
&data key="d0"&
&y:ShapeNode&
&y:NodeLabel visible="true" autoSizePolicy="content"&n2&/y:NodeLabel&
&/y:ShapeNode&
Attributes values
Attributes values have to be set within the node element as the following example:
&node id="n0"&
&data key="d0"&green&/data&
Basic Sample
&?xml version="1.0" encoding="UTF-8"?&
&graphml xmlns="http://graphml.graphdrawing.org/xmlns"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns
http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd"&
&graph id="G" edgedefault="undirected"&
&node id="n0"/&
&node id="n1"/&
&edge id="e1" source="n0" target="n1"/&
&/graphml&
With one attribute example
&?xml version="1.0" encoding="UTF-8"?&
&graphml xmlns="http://graphml.graphdrawing.org/xmlns"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd"&
&key id="d0" for="node" attr.name="color" attr.type="string"&
&default&yellow&/default&
&key id="d1" for="edge" attr.name="weight" attr.type="double"/&
&graph id="G" edgedefault="undirected"&
&node id="n0"&
&data key="d0"&green&/data&
&node id="n1"/&
&node id="n2"&
&data key="d0"&blue&/data&
&node id="n3"&
&data key="d0"&red&/data&
&node id="n4"/&
&node id="n5"&
&data key="d0"&turquoise&/data&
&edge id="e0" source="n0" target="n2"&

&edge id="e3" source="n3" target="n2"/&
&edge id="e4" source="n2" target="n4"/&
&edge id="e5" source="n3" target="n5"/&
&edge id="e6" source="n5" target="n4"&
