Kontrast: Interactive data visualization
Our software Kontrast allows you to create interactive visualizations from your data and equations – ideal for science, engineering and teaching.
Kontrast visualizes your data as point, line, area or volume plots with logarithmic or reciprocal axes mappings, color, opacity and thickness coding, …
Interactive visualizations created with Kontrast allow you to explore a larger parameter space and communicate data more clearly compared to static figures.
Kontrast excels in speed by maximizing the use of graphics acceleration and background computations. Even large data sets can be updated and rendered frequently.
We used Kontrast to create the following examples from various disciplines such as physics, chemistry, biology, medicine and meteorology. With Kontrast, you can create and publish interactive visualizations for your project as well.
The examples run directly in your browser (click to start).
Kontrast for scientists
Present your data
In interactive visualizations, data and parameters can be adjusted live.
Increase information content
Interactive visualizations allow to clearly communicate complex dependencies and large parameter spaces.
Interactive visualizations make it easy to quantitatively explore equations and models.
Kontrast for lecturers
Interactive visualizations make data and equations come to live and invite to explore.
Encourage independent learning
In interactive visualizations, the learning content is acquired actively and independently.
Interactive visualizations lead to
learning by doing.
Kontrast for publishers
A new digital format
Interactive visualizations allow to communicate science in a way that far exceeds the possibilities of print media and static e-books.
An active role for the readers
In interactive visualizations, the readers decide from which perspective they view the contents.
For a broad audience
Kontrast runs in web browsers – regardless of the operating system – on computers, tablets and mobile phones.
What we offer
Software library Kontrast
Workshops and training
We offer workshops on a variety of visualization and simulation topics, such as basics in visualizations and Monte-Carlo methods.
Visualizations as a service
From virtual lab courses to custom interactive research data analysis interfaces — We can be your project partner for custom interactive visualizations.
Kontrast: Future-proof by design
Are you able to re-run your analysis scripts from years ago?
Kontrast runs locally whether you are connected to the internet or not. Your data always remains in your control and you can publish only what you want to publish.
Kontrast ships fully self-contained and does not depend on any third-party libraries that need to be installed or managed. A text editor is all you need to get started.
As a vendor-independent and operating-system-independent platform, web browsers have a proven record of remaining backwards compatible.
