The program generates mathematical function values and plots them. For standard $x-y$ plots, where $y=f(x)$, $x=t$. For more general parametric mappings: $\mathbb{R} \rightarrow \mathbb{R}^2$, i.e., $t \rightarrow (x,y)$, e.g. $x=\cos(t)$ and $y=\sin(t)$ for a unit circle. The numerical format is in C-style (see e.g., the printf() statement). The program plots the graph for $(x,y)$ represented by the parametric equations. Multiple graphs can be added one after the other.
