I want to plot a very large dataset and therefore I need to use very small points or lines. It seems Thickness and Pointsize has a lower limit. Am I right?
po = RandomReal[{-1, 1}, {10000, 2}];
Graphics[{Thickness[0],Line[#] & /@ ({po[[1 ;; -2]], po[[2 ;;]]}\[Transpose])}]
Graphics[{PointSize[0], Point[#] & /@ po}]
Note that AbsolutePointSize and AbsoluteThickness give similar results.
