Function Graph Generator

Plots mathematical functions by parsing a user-provided expression and sampling over a defined x-range. It is designed for students, educators, researchers, and developers needing quick, reproducible graphs for analysis or documentation.
Conceptually, the tool separates input, evaluation, and rendering. It evaluates y = f(x) at evenly spaced x-values, collects (x,y) pairs, and outputs a graph-ready representation. It supports common functions include polynomials, trigonometric, logarithmic, and exponential forms, including composed expressions such as sin(x^2) or exp(-x).
Core value lies in deterministic sampling, clear data structures, and export options. Users can compare multiple expressions in one plot, adjust sampling density, and export the graph as SVG for vector quality or PNG for raster use. The tool also exposes the underlying data to enable programmatic reuse.
Unique differentiators include a safe expression evaluator with a math namespace, explicit domain control, and straightforward export formats. It is designed for integration into notebooks, teaching materials, and automated pipelines where reproducibility and precision matter.
