Organization Chart Visualization

Create an interactive organization chart using a professional diagramming library

An organization chart (often called organigram, or organogram) shows the internal structure of an organization. It describes the relations and hierarchy inside the organization. The members (employees, positions) are usually represented as boxes, often containing further information such as name, contact information, sometimes photos. Structure-wise, such a diagram is a tree, which itself is a special kind of graph.

Organization Chart

Building an organization chart visualizer or editor from scratch can be a challenging task. However, developers can save a lot of money, time, and workforce by using a software library that provides ready-to-use components for this task. yFiles is a commercial programming library that facilitates the creation of organization chart editors. yFiles is available for many different platforms.

Visualizing the Members

In an organization chart, it is common to visualize a member (e.g. an employee) as a box or card, which shows further information about the member. Besides the name, this often is the member’s position, contact information like phone number, and email address. Often, a photo and information about the member’s current status complete the information.

Different Visualizations of Members of an Organization Chart

yFiles supports arbitrary visualizations for elements. Particularly, the use of platform-specific technologies like SVG or XAML allows for the creation of complex styles with familiar tools.

Managing Large Organization Charts

Large-scale organization diagrams, such as the structure of a large corporation, quickly become crowded and confusing. Several techniques may be applied to improve their readability.

Level Of Detail

Depending on how far the diagram is zoomed out, omit some node information from the display. For example, addresses and telephone numbers needlessly clutter the diagram if one was to try getting an overview. You may want to reveal this information at an appropriate zoom level only. One might even go so far as to display simple icons for persons if sufficiently zoomed out.

The above example was created using yFiles. A highly flexible visualization is one of the key features of this commercially available software library.

Collapsing of Substructures

As with all large diagrams, you would want to filter down on the relevant data. So it is sometimes convenient to hide multiple entities altogether. To show a rough outline of a company structure, for example, you would typically hide away all nodes beneath the executive level. Whereas if you wanted to focus on a particular branch, displaying the board of directors is a moot point. Thus ideally, a way to hide an entity’s child and parent nodes is needed.

The above example was created using yFiles. It takes advantage of yFiles’ filtering capabilities combined with the use of interactive elements (for example, buttons) as part of the visualizations.

Examples and Source Code

The commercial programming library yFiles provides components for the visualization and the creation of diagram viewers and editors. It comes with a Organization Chart Sample Application that shows how to create an interactive organization chart. The employees are visualized with different levels of detail based on the current zoom level.

The source code of the Organization Chart Sample Application is part of all yFiles packages and available on the yWorks GitHub repository:

Choose from a range of different centrality measure implementations, automatic clustering algorithms, network flow algorithms, reachability and connectivity algorithms, pathfinding variants, cycle, and dependency analysis algorithms. For the best user experience, use the results to drive the visualization, interactivity, and layout.

What parts of yFiles can be customized?

yFiles has the most flexible, extensible, and easy to use diagramming APIs that are available commercially. Every aspect of the functionality is customizable with options ranging from high-level configuration settings, down to low-level implementation overrides: data acquisition, import, graph creation, display, interaction, animation, layout, export, printing, and third party service connectivity.

How can I get my data into yFiles?

End-users don’t need to create the diagrams from sketch or use a specific file format. yFiles lets you import graphs from any data source that is accessible via an API. Developers can populate the in-memory model using an intuitive, powerful API, directly connecting to their preferred data sources. Diagrams can be updated live in response to external events and changes.

How can I get my diagrams data back from yFiles?

The in-memory graph model lets you export all the information to any system and file format. There are built-in export options to various file and image formats, but as a developer, you can create your own glue code to connect to arbitrary data storage systems and third party services.

Is the diagram size limited?

Theoretically, the only limiting factor for the number of graph elements is the size of the computer’s memory. In practice, performance is also a limiting factor. For the vast majority of use-cases, yFiles delivers best-in-class performance out-of-the-box. For very large visualizations and data-sets, there are options available that let developers tune between features, running-time, and quality of the results. yFiles can deal with graphs of any size and is only bound by the memory available and the runtime complexity of the algorithms. Large graphs may require adjusting the default settings and performance depends on more than just the number of elements in the diagram, but also the structure of the graph, the algorithm and configuration, as well as platform and hardware capabilities.

Who is using yFiles, already?

Customers from almost all industries all over the planet have been using yFiles for nearly twenty years, to create both internal and customer-facing applications and tools. Clients include both single developers and the largest corporations and organizations in all of academia, public and governmental services, and of course, the commercial space. See the references for a non-conclusive list. Naturally, there are the big well-known software corporations among yWorks’ customers (unfortunately only some of them allow yWorks to list them on the references page), but there’s also a great lot of companies that are not traditionally known for software, but who still have their own IT departments create software for their intranet or customer-facing applications. And last but not least, smaller companies without IT departments that let third party implementors create useful diagramming applications with the help of yFiles for them. yFiles at its core is a generic diagramming component that is use-case agnostic and can be used to create graph and diagramming-centric applications for any business domain that requires working with or displaying connected data.

How long did it take to implement yFiles?

yFiles started as a university project at the University of Tübingen in the late 1990s. Since 2000, yWorks has taken over all development and has been working continuously with a core layout-team of two to eight developers on improving the layout algorithms. The layout algorithms alone, as of 2021, took more than seventy development years to implement. A team of more than 25 developers has been working on the implementation for the visualization and interaction and the support for the various platforms yFiles supports, totaling in more than a hundred years of development for the visualization. Porting yFiles to a new platform in the past took between three and about 15 development years. Most platform variations were implemented in between six and ten calendar months.

How long has yFiles been around?

yFiles started as a university project at the University of Tübingen in the late 1990s. The company yWorks was founded as a spin-off of the university in 2000 when the first commercial customers wanted a license for yFiles. Since then, it has been developing and improving the library. It all started as a Java library, and over time, yWorks improved and even rewrote large parts of the library to add new features and support new platforms.

Who is the company behind yFiles?

yWorks is the company behind yFiles. It was founded as a spin-off of the University of Tübingen in the year 2000 specifically for licensing and supporting yFiles commercially. The German company is a privately-held, headquartered in Tübingen. More than 30 employees are working at yWorks, over 20 of which are developers, working on yFiles and the tooling around the libraries. The library developers also provide support and implementation services to yFiles customers. So as a developer, you will get first-class, highest level support directly from the team that implements the libraries.

What does yWorks specialize in?

Since 2000, yWorks is dedicated to the creation of professional graph and diagramming software libraries. The software yWorks creates, enables customers to realize even the most sophisticated visualization requirements to help them gain insights into their connected data. Their main product is the software programming library family yFiles, which is the most sophisticated and complete solution available for diagramming applications on the market, supporting the broadest range of platforms, integrations, input methods, data sources, backends, IDEs, and programming languages. yWorks has set a track-record in providing the most extensive layout and diagramming solutions for developers on all major platforms. In addition to creating, maintaining and supporting the libraries, yWorks also provides professional consultancy services in the area of visualization and diagramming. In addition to that, yWorks also provides a set of smaller software tools, both free and commercial, end-user facing and for software developers, closed-source and open-source.

Does yWorks own all the intellectual property for yFiles?

yFiles does not depend on any third party library, except of course at runtime, where it depends on the runtime of the platform. yWorks owns the IP for all implementations in the core yFiles library. Some demos show the integration and make use of third party software, but they are not required for other cases.

Which papers and algorithms does yFiles implement?

The list of algorithms implemented by yFiles is long. For the common graph algorithms, we use the traditional implementations with the standard optimizations. For many of the layout algorithms, ideas for the implementation base on publicly available papers. Some algorithms (specifically the orthogonal layout and the balloon layout) we created and helped with the creation of the algorithms and (co-)published the papers for the algorithms. Most layout algorithms have been vastly modified, tuned, and enhanced, though, and don’t follow the original implementation ideas, anymore. yWorks added useful features to these implementations to make the algorithms work in less theoretical environments. We removed previously existing constraints of the original implementations and added new ideas to make the algorithms useful for real-world usage. For most of these changes and improvements, no papers have been published.

Can I get the papers for the layout algorithms used in yFiles?

For some of the algorithms, you will find papers that describe the core idea of the layout algorithms. For most algorithms, yWorks massively enhanced and modified the algorithms to support more advanced features that are frequently required in real-world diagrams. For these modifications, we did not publish any papers. As a commercial yFiles customer, you can obtain a license to the source code of yFiles where you can read, learn about, and modify the algorithms in documented source code form, according to the license terms.
