Graph Markup Language Format | The GraphML Team | Data Files |
GraphML .GRAPHML is an XML-based file format for graphs. It is commonly used to store and exchange graph structure data between different applications. Originally developed by Grapheine, the GraphML standard was adopted by many tools and libraries, such as yEd3, that use the format to share graph data.
GraphML files are typically used to represent networks, flowcharts, user interfaces, timelines, genealogies, social networks and diagrams. These files are composed of a plain text structured as XML and can be opened with a text processor or a graph editor, such as Graphviz or yEd3. In order to render a GraphML file in a graph editor application, every node in the file needs to have x/y coordinates established.
GraphML File Extension Details
The GraphML file extension is used for files that are written in an XML-based language made up of hierarchically structured elements. A valid GraphML file must adhere to a set of specific rules established in the which define the pieces of information needed by the GraphML markup language interpreter.
Typically, GraphML documents are written with an ".xml" file extension. The same can be done with GraphML files although they are mainly associated with the ".graphml", ".graph" and ".gml" extensions. Other related graph-based formats include DOT .DOT, GXL .GXL, RDF/XML .RDF, VGL .VGL, Visio XML Drawing .VDX and XLST .XSLT.
Programs for WINDOWS system

Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .GRAPHML) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .GRAPHML extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .GRAPHML file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .GRAPHML extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .GRAPHML extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .GRAPHML file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .GRAPHML file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .GRAPHML file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .GRAPHML file) will be extended to the maximum.
It is also good to check
- if the .GRAPHML file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
