What is Data Visualization ?
Data visualization is the process of representing text,numeric data and information visually, using graphs, charts, diagrams, and other visual aids. The main purpose of the data visualization is to present the complex data into understandable format and get the most information out of it easily.
Using the data visualization people can find the pattern , trends and other insights regarding any type of data .these pattern and insights can be useful for further development of the project.
Data visualization is widely used in many fields, including business, science, engineering, healthcare, and social sciences. It can help people make better decisions based on data-driven insights and solve the various business problems and run the project effectively.

Scala
Scala is a high-level, general-purpose programming language that combines object-oriented and functional programming paradigms. It was created by Martin Odersky and first released in 2004. Scala runs on the Java Virtual Machine (JVM) and is interoperable with Java, which allows developers to use both languages in the same project.
Scala is commonly used in web development, data processing, and big data applications. Many popular frameworks, such as Apache Spark, use Scala as their primary language. Scala is also used in the development of scalable, distributed systems, and its functional programming features make it well-suited for parallel and concurrent programming.
Scala’s syntax is concise and expressive, which reduces the amount of code needed to perform certain tasks. Scala also supports immutable data structures and higher-order functions, which makes it well-suited for functional programming. Additionally, Scala provides advanced features such as type inference, pattern matching, and implicit parameters, which can help to reduce code complexity and increase code reuse.
Following are a few scala libraries:
