The most basic code structure for a word cloud is as follows:

    wordcloud(vector_of_word, vector_of_frequencies, minimum_frequency)

This code will create a basic black-and-white word cloud, but if you want to create a color visualization and the color comes from different sources, then you can specify using the color parameter. There are various other options available in the word cloud function. By typing help(wordcloud), you will be able to explore this further.
