Word Cloud with Python Tutorial

Word clouds are one of the most common methods of representing the textual dataset in a graphical format. A word cloud can also be used for sentiment analysis by analyzing text. In this article, I’ll walk you through a tutorial on word cloud with Python.

What is a Word Cloud?

A word cloud is more than a simple graphical representation of textual data. In data science, it plays a major role in analyzing data from different types of applications. A word cloud is a graphical representation of words, i.e. tags, which are used to represent the frequency of entities in a particular data set.

In Data Science, word clouds are mainly used to visualize the most frequent words in a graphical representation to identify keywords of different sizes and colours based on the frequency of the words.

In general, the text represented by word clouds is visualized in such a way that the most frequent words in a particular piece of text appear larger than the less frequent words.
