Curve Plotter

Overview

Given a function of x and y, the application plots the resulting curve and continuously calculates the nearest point to the cursor position, then draws the tangent line at that point.

The result is a compact tool that combines graphics programming, numerical methods, and responsive input handling, all running natively in the browser via WebAssembly.

Highlights

• Plots a curve from a user-defined function of x and y.
• Finds the point on the curve nearest the cursor in real time.
• Draws the tangent line at the selected point.
• Compiled with Emscripten to run in the browser with no install.
