grapher - an interactive web graphing utility.

Real grapher

Graphs arbitrarily many functions \(f: \mathbb{R} \longrightarrow \mathbb{R}\), in terms of a variable \(x\). It supports any function allowed by math.js, which does the parsing for the math expressions. Try it out!

Complex grapher

Graphs functions of the form \(f: \mathbb{C} \longrightarrow \mathbb{C}\) using domain coloring. I wrote a custom parser for this utility, so fewer functions are supported. Try it out!

3D real grapher

Graphs functions of the form \(f: \mathbb{R}^2 \longrightarrow \mathbb{R}\), written in terms of the variables \(x\) and \(y\). It supports any function allowed by math.js, which does the parsing for the math expressions. Try it out!
