Instead of traditional word cloud generation from user review via tools like Wordle etc.. I have done manual content analysis of the reviews and identified specific attributes within the user review. Now, I want to visualize the closeness / distance of these attributes identified.

For example, a single review of a restaurant can be talking about various aspects of restaurants, such as some may be talking about cleanliness & hygiene, food qualities etc. Thus, multiple reviews of different restaurants have talked about various different aspects of the restaurants, which I have manually classified. Now, I want to visualize the relationships between these attributes based on their occurrences in the review. I am unable to find a free and user friendly tool to do the same. If someone can please suggest me. Also, I am planning to use chi-squared distance to find the association between attributes. Will it be right? Please advice
