ii. Word Cloud

A word cloud is an illustration of text data, with the size of each word

based on how often or important it appears in the text. It gives an

overall look at the most popular or important words in a way that is
pleasing to the eye. The bigger and stronger a word is in the word

cloud, the more often it is used in the text. People often use word

clouds to quickly see what the main ideas or buzzwords are in a paper,
website, or set of data. It gives a short, easy-to-understand outline of

the text by putting emphasis on the most important words. Word cloud
generators can be used as tools or libraries in different computer

languages. They can be changed by changing the colours, fonts, and
style. Figure 2.6 shows an example of the text data that have been

interpreted into word cloud.

iii. Correlation Matrix

Correlation matrix is a way to show data in the form of a grid with

rows and columns. It helps find patterns, connections, and differences
among factors or things. Cells in the matrix show data numbers, and

colours are often used to show how strong the data is. Correlation
matrix are useful for analysing data, networks, and other things. They

give an organised view of the data, which makes it easier to look at
and understand. Figure 2.7 demonstrates an example of the

relationship between variables in each table cell.
