Webbclass LineString(coordinates) The LineString constructor takes an ordered sequence of 2 or more (x, y[, z]) point tuples. The constructed LineString object represents one or more connected linear splines between the points. Repeated points in the ordered sequence are allowed, but may incur performance penalties and should be avoided.
