Description

After discovering the basic concepts and techniques related to visual representation of data, you will learn to develop data visualization applications based on DataVisualisation's main Java/JavaScript tools and frameworks.

Who is this training for ?

For whom ?

Java and/or JavaScript developers wishing to create data visualizations in a practical manner.

Prerequisites
