Word Cloud
A Word Cloud Chart is a visualization that displays text data in which the font size of each word represents its frequency or importance within the dataset. Larger words appear more often in the source text, while smaller ones appear less frequently.
Although word clouds are not always the most precise analytical tool, they are widely used in infographics, survey analysis, and exploratory text mining to highlight dominant terms and uncover visible patterns.
Best Situations to Use
Use a Word Cloud chart when you want to:
Analyze text data from surveys, reviews, or social media.
Identify trends or themes that may be hard to spot in tables.
Provide an engaging infographic-style visualization for presentations or dashboards.
Example: Analyzing customer feedback using a word cloud can quickly highlight terms such as “service,” “price,” or “delivery,” revealing common concerns or praise.
