Visualizing an OrientDB Graph Database

Gain insights about your OrientDB database relationships through diagram visualizations

What Is OrientDB?

OrientDB is a multi-model database capable of efficiently storing and retrieving data like all traditional database systems while it also supports new functionality adopted from graph and document databases. It is written in Java and belongs to the NoSQL database family.

One of the core features of OrientDB is the support of multi-model objects, like Document, Graph, Key/Value, and Real Object. Each of these models can be manipulated using a separate API. Besides, OrientDB has been optimized in terms of performance on both read and write operations.

Why Use a Graphical Representation of OrientDB Data?

Visualizing a graph database is considered to give a tremendous benefit to the users as it offers a better insight into the content of the data. The user does not have to dig into the database’s raw data, making it easier to investigate the data, understand their relationships, and identify possible patterns and structures. Also, the user can interact with the visualization and interactively explore the data without any previous knowledge of the query language of the database.

Exploring the Data

Therefore, being able to provide a high-quality visualization of the OrientDB could be a powerful solution when handling or analyzing vast amounts of data.

Challenges of Graph Database Visualizations

Although the nature of the connected graph data is predestined for visualization, it is still a challenging task because of the sheer amount of data that it usually contains.

Typical Hairball Network

The first step in presenting the data is to query it from the database. After that, the query result must be arranged meaningfully to create a human-readable representation of the raw data. Additionally, a styling that differentiates the different types of entities and relations and presents the properties associated with the items helps to interpret the data at a glance. Furthermore, the performance should allow for an interactive exploration of the data.

Creating a Graph Visualization From OrientDB Data

OrientDB offers a graph editor that visualizes the data and allows interaction and data modification. More precisely, the user can write a query, and present the result as a graph in the graph area. Additional functionality like node addition, node deletion, and relationship navigation is also supported.

While this can be sufficient for many data sets, there exist many more complex use cases that either require specific interactions (e.g., drill-down, merging, filtering) or in which specific arrangements have to be applied to identify certain substructures in the data.

Utilizing a Sophisticated Visualization Solution

A comprehensive visualization solution provides a means to create a client that enables users to gain more insight into the stored data. It can be tailored to specific requirements related to element visualization, element arrangement, or interactions.

yFiles for HTML is a commercial programming library explicitly designed for diagram visualization and is a perfect fit for the challenges of graph database visualization. Its sophisticated layout algorithms can easily transform the data in a readable, pleasing, and informative network. The different layout styles, for example, hierarchic, organic, tree, circular, or radial, enable the user to intuitively identify structural characteristics of the data, such as hierarchy, connected components, or rings.

Furthermore, yFiles for HTML comes with a multiplicity of graph analysis algorithms (e.g., centrality, clustering, path algorithms, etc.) that can be applied to the data model to add more value to the data.

Visualizing OrientDB with yFiles for HTML

OrientDB supports a variety of different APIs to access the data, among which SQL is often used to query the database. The easiest way is to convert the result in JSON format data objects with multiple properties that represent the stored entities.

yFiles for HTML comes with a Graph Builder, which transforms the raw data from the JSON result into a graph structure. After building the graph structure, the full power of the yFiles for HTML diagramming library is at your disposal.

Data-Driven Visualization

A good visualization provides insights into the data that are not obvious by looking at the raw data. yFiles for HTML offers several ways to use the data from the OrientDB database to create a rich and meaningful representation. The user can take advantage of the powerful data binding capabilities to create item templates that utilize the labels and properties of the OrientDB data.

Data Binding

Automatic Arrangement

Automatic layouts can give you different perspectives on your data structure. In particular, they make it easy to identify substructures in your data like connected components, chains, circles, stars, and hierarchies. yFiles provides an extensive set of sophisticated, highly configurable automatic layout algorithms that arrange your data in a clear, concise, and readable manner in the blink of an eye.

Organic Placement
Hierarchic Placement
Orthogonal Placement
Circular Placement

Powerful Exploration

An interactive application can provide much more functionality than a simple static representation. With yFiles for HTML, a graph visualization can be augmented with a considerable set of interactive features:

  • Grouping lets you combine similar or related items to reduce visual complexity

  • Drill down helps to explore specific parts of the data

  • Filtering can be used to reduce the number of displayed entities without any additional database queries

  • Data exploration and interactive modification is possible by mouse, keyboard and touch gestures

  • Animations can help to provide a pleasant user experience

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.

Is a server required to host a graph drawing application?

yFiles for HTML does not require an active server component.

Do I need server-side rendering to render my diagrams?

No. The visualization part of yFiles for HTML is an interactive JavaScript component that runs inside the browser on the client. As such, rendering the diagram on the server would not result in an interactive diagram, but rather a static image. yFiles for HTML does not require an active server component, and the page that hosts the diagram component can be rendered on the server with static server-side rendering techniques that create the complete DOM on the server. yFiles for HTML still needs to be loaded on the client to provide interactive features like zooming, scrolling, editing, and animating the diagram.
