Summer is coming and I watch the changes of position of the sun's elliptic in the sky. Does anyone know of a good weblink or simulation that shows the path of the sun at varying times of the month?

Thank you, but I am familiar with the analemma which is the position of the sun at a fixed time of day. I am interested in the path of the sun from sunrise to sunset (the arc) and seeing how its eastern and western points vary over the time of year.

I actually found a link that seems to do this:

That's usually referred to the zodiac.(at elast the variation along th ecliptic). If you mean the variation due to the tilt of the earth's axis, that seems fairly obvious.
