This function generates a word cloud based on a list of keywords and weights.
Please upload a single CSV file (utf-8 encoding) with two columns - the first containing words and the second weights. The first row (which must have a header) will be ignored. Through the form, you will be able to choose the shape and color of the word cloud and the maximum number of words to show.
Here is a legend of the possible color sets provided by the app (please read the color set name in the cloud). Please consider that colors are randomly assigned to each word.
