The Anatomy of an Argument

Run MicroSim in Fullscreen

How to Use This MicroSim

Click on any node in the diagram to open a side panel showing its full definition, a concrete literary example, and diagnostic questions to help you find it in a real text. Use the dropdown to switch example sources among Letter from Birmingham Jail, Lincoln's Second Inaugural Address, and a sample student essay — all node examples update automatically. When you are ready to practice, click "Build My Argument" to enter your own claim, evidence, warrant, and counterclaim; the diagram assembles your argument into a color-coded visual display.

Learning Objective

Apply (L3 — Apply) the Toulmin model to identify and label the components of a real argument — claim, evidence, warrant, counterclaim, rebuttal — in a provided sample text.

Specification

The full specification below is extracted from Chapter 6: Informational Text — Rhetoric, Argument, and Rhetorical Appeals.

Type: Interactive Infographic
**sim-id:** argument-anatomy-explorer<br/>
**Library:** vis-network<br/>
**Status:** Specified

**Learning Objective:** Apply (L3 — Apply) the Toulmin model to identify and label the components of a real argument — claim, evidence, warrant, counterclaim, rebuttal — in a provided sample text.

**Description:** A node-and-edge diagram showing the six Toulmin argument components. Six labeled nodes: Claim (center, large, deep blue #1565C0), Evidence (left, green #2E7D32), Warrant (bottom center, amber #F57F17), Backing (bottom-left, light amber #FFE082), Qualifier (top-right, teal #00695C), and Counterclaim/Rebuttal (right, red #C62828). Directed edges show how each component relates to the Claim node.

**Default node display:** Each node shows its name and a one-line definition.

**Interactions:**
- Clicking any node opens a side panel with: (1) full definition, (2) a concrete example from Martin Luther King Jr.'s "Letter from Birmingham Jail," (3) a "How to find it" checklist of 2–3 diagnostic questions.
- A dropdown menu switches the example source among: "Letter from Birmingham Jail," Lincoln's Second Inaugural Address, and a sample student argumentative essay. All node examples update when the source is switched.
- A "Build My Argument" button opens a guided entry form: the user selects or types a claim, then fills in evidence, warrant, and counterclaim fields. When completed, the diagram assembles the components into a color-coded display with the user's text in each node.

**Canvas:** Responsive, minimum 500px wide, minimum height 400px. Re-renders on window resize.

**Visual style:** White background, colored nodes, directed curved-arrow edges, clean sans-serif labels.
