To get Matplotlib to use LaTeX for π, you need (escaped) dollar signs and
also to escape the backslash: title("\$\\pi\$ = $pi"). Or you can use
Unicode for \pi: title("π = $pi").
Note that string(pi) is "π = 3.1415926535897...", however, so for this
particular example you probably want
title("π ≈ $(Float64(pi))")
