The benefits of diagramming

Data visualization — creating graphs or diagrams — is a key technique for analyzing large amounts of information 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.

Tap into a human talent: pattern recognition. Graph visualization helps you to recognize patterns and trends at a glance. What’s more, graph analysis algorithms can be used to visualize key information within the data.
Clear & Easy
People are very visual. Seeing data as graphs helps you absorb the information faster, explore it intuitively, and work with it more easily. Visualization can help monitor large networks and improve all types of workflows.

What is a diagramming SDK?

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

The yFiles SDK goes even 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”!
