The benefits of diagramming

Data visualization — creating graphs or diagrams — is a key technique for analyzing large amounts of data and making data-driven decisions. In our Big Data world, this has become even more important.
Understanding trends, patterns, and outliers is crucial to successfully navigating digital transformation in Industry 4.0.
Work with your data and observe how real-time changes affect aspects of the graph. This is extremely helpful for understanding past developments, present events, and future projections.
Change your perspective with just one click: Graph visualization lets you get a broad overview or zoom in to explore a specific area in detail.
Visualization helps you recognize correlations and developments at a glance. In addition, graph-analysis algorithms can be used to extract important information hidden in the data.
Clear & Easy
People are very visual. Seeing data as graphs helps all of us absorb information faster and work with it intuitively.

What is a diagramming SDK?

If you want to assemble a car, you need a kit containing parts, tools, and instructions.
A diagramming SDK (“software development kit”) or diagramming library offers all of this for creating diagrams and visualizations. It’s an easy, flexible way to visualize data without having to reinvent the wheel (or, in this case, nodes and edges).

The yFiles SDK takes this one step further and organizes your data into a beautiful graph layout of your choice, with just one click. That’s why we say our SDK also stands for “superior diagramming kit”!

From southern Germany to Silicon Valley

Numerous world-renowned companies, research institutes, and universities rely on the expertise of yWorks.
