Points To Line

This node generate lines from points according to group id and serial label. The result table contains one LineString object per group value. Each constructed LineString object represents one or more connected linear splines between the given points of a group ordered by the serial column. Repeated points in the ordered sequence are allowed, but may incur performance penalties and should be avoided. A LineString may cross itself. A LineString has zero area and non-zero length.
