Mandala & Microsearch
Mandala- This is a tool of conceptual visualization showing the relationships in graphics rather than a summary of a table between terms and documents. It is useful in helping readers figure out the key information of documents.
Microsearch - This is a tool that can help readers to see the frequency and distribution of terms in a corpus by table columns, rather than in visualization of bubbles, bubble lines, or cirrus (word cloud).
