Title: Chordratio & new chord SVG

I've added the chordratio layout which takes a rectangular array of relationships between entities. Each row represents an entity, each column is that entity's contribution to some total value for the column. I also changed the svg chord to a cubic spline in an attempt to reduce path self-intersections.
