I just added an iteration operator to https://math.berkeley.edu/~kmill/tools/zgraph/zgraph.html

Example: z^2-0.4+0.57i+0.03*e^(i t) iterate 150

Use shift+left and shift+right to adjust the rate at which t varies. It starts at constant 0.

It also now has a composition operator: "z^2 then e^z then 1/z" computes 1/(e^(z^2)).

The precedence rule is that "f1(z) iterate 3 then f2(z) iterate 3" is "(f1(z) iterate 3) then (f2(z) iterate 3)", which is f2(f2(f2(f1(f1(f1(z)))))).



Neat :)
