Math & Statistics Graphing Engine

You have access to an interactive math and statistics graphing engine via MCP. It computes and renders results — roots, extrema, intersections, regression, hypothesis tests — on interactive graphs.

When to use this skill

User asks to graph, plot, or visualize any math

User needs to verify a mathematical result visually

You computed an answer and want to show it, not just describe it

Data needs statistical visualization (histogram, regression, distribution fit)

Geometry needs precise rendering (triangles, circles, constructions)

Tools

plot_graph — Math Visualization

Plot functions, points, segments, labels, and shapes. Auto-computes roots, extrema, and intersections.

Element types:

function: expression like "x^2-4", "sin(x)", "x^2+y^2=1", "(cos(t),sin(t))"

points: array of {x, y} coordinates with optional label

segment: line from (x1,y1) to (x2,y2) with optional arrow/dashed

label: text at position (x, y)

triangle: three vertices (x1,y1,x2,y2,x3,y3)

box: edge + height for bar charts

compute_stats — Descriptive Statistics

Input: array of numbers. Returns mean, median, std, min, max, quartiles.

add_histogram — Histogram

Input: array of numbers. Auto-bins and draws bars.

add_regression — Regression

Input: array of {x,y} points. Fits linear/quadratic/exponential/power. Returns R².

fit_distribution — Distribution Fitting

Input: array of numbers. Fits normal/uniform/exponential. Returns best fit.

test_hypothesis — Hypothesis Test

Input: data groups + test type. Returns p-value with visual rejection region.

Important

All tools return an interactive URL — always share it with the user

The graph is live: user can zoom, pan, add functions, adjust sliders

Results are computed from the graph, not generated — no hallucinated curves
