n = 200
particle = Transpose@{Range[n],
                      RandomInteger[{15,25},n],
                      RandomInteger[{0,200},n],
                      RandomInteger[{0,200},n]};
Show[Graphics[{PointSize[#2*.001],Point@{#3,#4}}& @@@ particle],
Frame->True, PlotRange->{{-5,205},{-5,205}}, AspectRatio->Automatic]
