## Tracing a portion of a graph and moves along that portion using Manim updater

This post is about Manim code for tracing a portion of a graph and assigning a `dot`

to move along that portion. In this animation, we created a cubic graph with *y* = *x*^{3} - 3*x*^{2} + 2*x* + 1.5 and trace a portion of this curve between *x* = -0.3 and *x* = 2.2 then assign a point to move along this portion.
