Here is a macro tool that draws circles. Double click on the tool to
change the circle diameter. Double click on the eye dropper tool to
change the color used to draw the circles. Use the Analyze>Set Scale
command to define the unit and scale. Add the code to
ImageJ/macros/StartupMacros.txt to have the tool added to the tool bar
when ImageJ starts.

var diameter = 200;
macro "Circle Tool - C00cO11cc" {
getCursorLoc(x, y, z, flags);
getPixelSize(unit, w, h);
d = diameter;
drawOval(x-d/(w*2), y-d/(h*2), d/w, d/h);
}
macro "Circle Tool Options" {
getPixelSize(unit, w, h);
diameter = getNumber("Diameter ("+unit+"): ", diameter);
}
