What is a Word Cloud?

A word cloud is a visual representation of text data where the size of each word corresponds to its frequency or importance in the dataset. For example, in a word cloud generated from a speech, the most frequently used words will appear larger and more prominent.

  • Quick Insights: Helps identify key themes or trends at a glance.

Word clouds are created using a simple yet effective algorithm:

  1. Text Input: The user provides a text dataset, such as a document, article, or social media posts.
  2. Word Frequency Analysis: The tool analyzes the text and counts how often each word appears.
  3. Visualization: Words are displayed in a cloud-like layout, with larger fonts for more frequent words.
