If the data you're collecting is not confidential, and small in nature, and would like to generate a word cloud fast (without programming), this website could be useful for you.
Scraping around 800 tweets on #happiness, I wanted to know what words people associated "happiness" with. The previous blogpost on how to scrape Twitter data can be found here. So after pasting all the tweets into the "Original text" box on the page, and clicking "Generate", I will get the word cloud easily.
Some user customization is possible, such as the font and color of the word cloud, as well as removing or editing words returned (by clicking on the words in the "Word list" that's located on the left hand panel).
If your data is confidential and large in nature, a more suitable solution would be performing text mining.
