This tool will be quite handy for exploring text data and making your report more lively. Many time we have seen a cloud filled with lots of words in different sizes,which represent the frequency or the importance of each word. This is called **Tag Cloud **or WordCloud.

- numpy
- pandas
- matplotlib
- pillow

The numpy libraries is one of the most popular and helpful libraries that is used for handling multi-dimensional arrays and matrices. it is also used in combination with pandas library to perform data analysis.
matplotlib is a basic library that enables many other libraries to run and plot on its base including seaborn or wordcloud.
The **pillow **library is a package that enables image reading, Pillow is wrapper for PIL- python imaging library.you will need this library to read in image as the mask for the wordcloud.
If you only need it for plotting a basic wordcloud, then pip install wordcloud
