points = {{0, 0}, {0, 1}, {1, 1}, {1, 0}};

att1 = {1, .3, .5, .7};

att2 = {.05, .1, .05, .075};

Show[Graphics[Transpose[
   {Hue /@ att1, PointSize /@ att2, Point /@ points}]],
 Axes -> True]

ListPlot[List /@ points,
 PlotStyle -> Transpose[{Hue /@ att1, PointSize /@ att2}],
 PlotRange -> {{-0.1, 1.1}, {-0.1, 1.1}},
 AspectRatio -> 1]

In version 6:

Graphics[Transpose[
  {Hue /@ att1, PointSize /@ att2, Point /@ points}],
 Axes -> True]

=============
I cannot find this in the help at all, although I am sure it is 
straightforward.

I have a list of coordinates of points points={{x1,y1},{x2,y2}...}
and two lists of attributes att1={a1,a2,..} and att2={b1,b2,...}

I want to do something like 
ListPlot[points,PlotStyle->{Hue[att1],PointSize[att2]}]
So I get dots at each point in colour att1 and size given by att2. I'm 
sure it's easy but I can't do it. I am using version 5.1

Many thanks,

Peter
