Figure 1 shows a flowchart that captures the overall functionality of virocon. A statistical model of the (offshore)
environment can be created by fitting a model structure to measurement data. Then, this statistical model can be used to
construct an environmental contour.

The class diagram is showing among others the class MultivariateModel, which
handles fitting a model structure to a dataset, the class DependenceFunction, which handles the dependencies between the
environmental variables and the class Contour, which handles contour construction. This class diagram was created for
virocon version 2.0.0

Figure 2 shows virocon's class diagram.
