Function Grapher
Interactive simulation — adjust parameters and watch the visualization update in real time.
How it works
Type a **y = f(x)** expression evaluated by **mathjs** (variable **x** only). The plot auto-scales **y**; **drag** on the graph to pan horizontally. **Zoom** squeezes or widens the **x** window about the center. Discontinuities and poles are drawn as separate segments.
Key equations
Examples: sin(x), x^2 + 2*x, exp(-x^2)
