1 # Type: flowchart
2
3 Sequential blocks connected by arrows, showing process / workflow / pipeline. Used for "how-it-works" visuals, onboarding steps, pipeline diagrams, sequential methodologies.

5 > **What flowchart means inside a PPT block**: the image internally shows 3-6 stages in a clear directional sequence. Unlike `infographic` (parallel zones), flowchart has **direction**. Unlike `framework` (hub + satellites), flowchart has **sequence**.

7 ## 1. Composition skeleton
8
9 Three sub-structures:
10
11 ### Sub-structure 1 — Horizontal flow (most common)
12
13 ```
14 ┌───┐ → ┌───┐ → ┌───┐ → ┌───┐
15 │ 1 │ │ 2 │ │ 3 │ │ 4 │
16 └───┘ └───┘ └───┘ └───┘
17 ```
18
19 ### Sub-structure 2 — Vertical flow
20
21 ```
22 ┌───┐
23 │ 1 │
24 └─┬─┘
25
26 ┌───┐
27 │ 2 │
28 └─┬─┘
29
30 ┌───┐
31 │ 3 │
32 └───┘
33 ```
34
35 ### Sub-structure 3 — Looping / cyclical
36
37 ```
38 ┌───┐ → ┌───┐
39 │ 1 │ │ 2 │
40 └───┘ └─┬─┘
41 ↑ ↓
42 ┌───┐ ← ┌───┐
43 │ 4 │ │ 3 │
44 └───┘ └───┘
45 ```

47 | LAYOUT | 3-6 stage blocks with explicit connectors (arrows or lines with arrowheads) showing direction |
48 | ELEMENTS | Stages visually consistent (same shape, similar size); connectors uniform stroke weight; arrowheads consistent style |
49 | NEGATIVE SPACE | Generous around the flow — stages don't touch edges, connectors don't crowd |
50 | DIRECTIONAL CLARITY | The flow direction is unambiguous |
51
52 ## 2. Text-policy variants
53
54 ### `text_policy: none`
55
56 Each stage contains an iconic symbol only. Stage labels added in SVG overlay below or above the image.
57
58 ### `text_policy: embedded`
59
60 Each stage may contain a short keyword (≤2 words) inside or beside it.

68 > Clean flat vector illustration flowchart banner. Four rounded-rectangle stages arranged horizontally across the canvas, separated by uniform gaps. Each stage is filled with primary deep navy `#1E3A5F`, with crisp 2px outlines and 8% soft drop shadow. Between each pair of stages, a thin uniform horizontal arrow with a clean triangular arrowhead in secondary `#F8F9FA` or near-black. The third stage (highlighted as the focal stage) has a thin accent gold `#D4AF37` ring around it — under 5% accent area. Each stage contains one simple iconic symbol in white — an input arrow, a gear, a magnifier, an output arrow respectively. Background field is secondary light gray `#F8F9FA`. Composed for a 1200×400 hero band with 14% inner padding. NO text, letters, numbers, or labels — SVG labels added externally. Color values are rendering guidance only.
