How Graph Plotter works

Uses math.js to evaluate your function expression at 500 points across the x range, then Plotly.js to render an interactive chart. Supports standard math functions (sin, cos, tan, exp, log, sqrt, abs, etc.) and operators (^, *, /, +, -). The chart supports zoom, pan, and PNG download via the toolbar.
