Concept-first toolbox
Learning Chaos With Figures
Toolbox Chaos is organized around the same teaching idea as the dictionary PDF: students learn faster when each concept is tied to a concrete graph. The overview shows the available workflows; the documentation explains how to read each graph in detail.
Read the visual theory primer ->Theory Through Graphics
The dictionary and web documentation connect definitions with reproducible figures, so students can read what each diagnostic is actually showing.
Separate Visual Tasks
A basin map, a coexistence comparison, a bifurcation diagram, and a Lyapunov plot answer different questions. The site keeps those workflows separated.
Reproducible Examples
Examples use explicit systems, parameters, initial conditions, projection choices, and retained windows so students can reproduce the plots.
Recovered exploration workflow
Sprott Explorer
The Sprott Explorer invites students to experiment with compact dynamical-system recipes inspired by J. C. Sprott's strange-attractor work. Load a generated example, change the projection or visual preset, and watch how a short code becomes a map, a flow, or a dense phase-space object worth investigating.
The public page uses reproducible educational examples, while the documentation explains the decoding logic, search filters, plotting choices, and parameter effects.

Working Pattern
A practical loop for moving from a first run to a figure worth saving.
Choose a visual question
Start from the graph you need: attractor, projection, bifurcation, basin, coexistence, FFT, Lyapunov, or Sprott exploration.
Load a coherent preset
Use a registered system so equations, parameters, initial state, and integration scale begin in a known range.
Run a low-cost pass
Use coarse grids, shorter sweeps, or fewer points to check whether the selected region is meaningful.
Refine one control
Change one value at a time: time step, total time, transient, parameter range, projection, or density.
Compare diagnostics
Use geometry, time series, basins, bifurcation, spectra, and Lyapunov estimates as complementary evidence.
Export the final figure
Increase resolution after the behavior is clear, then export the figure from the relevant tab.
Practical Guides
Guides keep concepts, parameters, basins, coexistence, bifurcation, and Sprott exploration as separate workflows.
Concepts and Visual Theory of Chaos
Definitions, figures, and reading strategies for first-time students of chaotic systems.
Lorenz Attractor Quick Start
Set up parameters, run your first simulation, and compare 3D and 2D phase portraits.
Bifurcation Diagrams
Compute parameter sweeps, Poincare sections, and Hopf examples with readable settings.
Coexisting Attractors
Compare selected multistability cases without confusing them with basin maps.
Basins of Attraction
Read basin colors and representative trajectories launched from different regions.
Sprott Explorer Guide
Understand codes, decoding, search, filtering, plotting presets, and parameter choices.
FFT and Spectral Analysis

Lyapunov Exponents
Visualize perturbation growth and read convergence-aware exponent estimates.
Visual Output Gallery
Attractors, bifurcations, Poincare sections, basins, coexistence cases, Lyapunov figures, and Sprott-generated graphics.
