Knots
Knots - This is a visualization tool representing terms as a series of twisted lines. This tool is a creative visualization that represents terms in one document as a series of twisted lines. Every occurrence isa term that is represented by a bend in the line, so the more twisted a line is, the more a term repeats; otherwise, straight stretches represent no occurrences. It isa fun way to help young readers ton understand the points of any bodies of text.
