IconVault's Function Grapher plots your math instantly on an interactive canvas. Type expressions like x^2, sin(x), or ln(x+1) into a hand-written parser that understands operators, parentheses, exponents, and common math functions, then watch the curve draw in color. Add multiple functions to compare them on the same axes.

Zoom and pan with the mouse to explore asymptotes, roots, and intersections up close, and toggle each function on and off without retyping it. It is free and runs fully in your browser: no server, no signup, just type and graph.
