# ASCII Visualizer Consistent, readable ASCII diagrams for architecture, workflows, file trees, and data visualizations. All output renders correctly in monospace terminals without external tools. **Core principle:** Encode information into structure, not decoration. Every diagram element should communicate something meaningful. ## Box-Drawing Character Reference This block intentionally shows multiple sets together as a key. Authors should use ONE set per real diagram; the `single-set` lint rule enforces this on production diagrams. <!-- ascii-lint-disable: single-set,single-arrow-style,density-min --> ``` default: ┌─┐ │ └─┘ ├─┤ ┬ ┴ ┼ emphasis: ┏━┓ ┃ ┗━┛ ┣━┫ ┳ ┻ ╋ title: ╔═╗ ║ ╚═╝ ╠═╣ ╦ ╩ ╬ soft: ╭─╮ │ ╰─╯ portable: +-+ | +-+ +-+ + + + Arrows: → ← ↑ ↓ ─> <─ ──> <── Blocks: █ ▓ ░ ▏▎▍▌▋▊▉ Status: ● ○ ✓ ✗ ⚠ ◆ ◇ ▶ ▷ ↑↓→ ▓▒░ (closed-set vocab — see rules) ``` ### Set Conventions (D8: intent-driven naming) Tokens live in `tokens.json`.
