Show more (or fewer) lines in a circle graph

When you create a circle graph only items with strong similarity are connected by lines in the graph.  

If the graph has no lines, or you want to show more lines (for example, you want to see weak as well as strong similarity), you can adjust the filters which determine the number of lines shown in the graph.
