"""
Ver. 1.0.0 (2024-02-06)
This module demonstrates and visualizes the native stream Clouds2D4C5000Dynamic which generates 5000
2-dimensional random instances that form 4 moving point clouds.
You will learn:
1) The properties and use of native stream Clouds2D4C5000Dynamic.
2) How to set up a stream workflow without a stream task.
3) How to set up a stream scenario based on a stream and a processing stream workflow.
4) How to run a stream scenario dark or with default visualization.
