Easy. Put it into RubberSheet and Image, with AutoAxes turned on. I've attached a net file. I create a vector of random 2-D positions in the unit square, pass it into Histogram requesting 20 buckets on a side, and render the result - a 2-D bar chart. For an interesting alternative, add Post(... "positions") after Histogram and before RubberSheet.

But then how do I visualize that result ? It does not appear to readily feed back into the Plot module. I want to simulate the scatter plot that I already have, but with a single colorized point at each [x,y] to indicate the number of occurences (many plotted points would overlap eachother, otherwise). Should I ditch the Plot module ?
