                 *

                 *
                 * `straight`:      Draws a straight line between the connecting
                 *                  points. Does not avoid other points when drawing.
                 *
                 * `simpleConnect`: Finds a path between the points using right angles
                 *                  only. Takes only starting/ending points into
                 *                  account, and will not avoid other points.
                 *

                 *                  only. Will attempt to avoid other points, but its
                 *                  focus is performance over accuracy. Works well with
                 *                  less dense datasets.

         * `fastAvoid`:     Finds a path between the points using right angles

                 *

                 * `straight`:      Draws a straight line between the connecting
                 *                  points. Does not avoid other points when drawing.
                 *
                 * `simpleConnect`: Finds a path between the points using right angles
                 *                  only. Takes only starting/ending points into
                 *                  account, and will not avoid other points.

                 *                  only. Will attempt to avoid other points, but its
                 *                  focus is performance over accuracy. Works well with
                 *                  less dense datasets.
