Create a map displaying the tracks specified. Tracks may be drawn in one specified color, with each separate track drawn in a different color from a specified palette, or as a series of closely spaced dots (which may be prodded into appearing as a line through judicious choice of point size and alpha) with the color varying based on speed and the chosen palette
