Analyze and enhance Obsidian documents with visual elements. Use when enhancing markdown documents with diagrams, graphs, or formulas.
Enhances Obsidian documents by converting ASCII diagrams to Mermaid/Desmos/TikZJax and formatting mathematical notation with MathJax. Use it to transform text-based visuals into clear, professional diagrams that improve comprehension.

Your goal is not to maximize visual content, but to add it only where it genuinely improves comprehension.

<ascii_detection> How to detect ASCII visuals:
Look for code blocks or preformatted text containing these patterns:
| Pattern Type | Characters | Example |
|---|---|---|
| Box drawing | ┌ ┐ └ ┘ │ ─ ├ ┤ ┬ ┴ ┼ | ┌──────┐ |
| Simple boxes | `+ - | _ /` |
| Arrows | → ← ↑ ↓ --> <-- ==> | A --> B |
| Tree structure | ├── └── | ├── src/ |
| Math symbols | Σ ∫ √ ∞ ≠ ≤ ≥ × | Σ(n=1 to ∞) |
| Graph axes | ^ at top, > at right | coordinate systems |
| Tables with ` | ` | ASCII tables |
Detection heuristic: If a code block has 3+ lines AND contains 5+ box-drawing or arrow characters, it's likely an ASCII diagram. </ascii_detection>
<enhancement_types> ASCII → Mermaid Diagram Detect and convert these ASCII patterns:
| ASCII Pattern | Convert To |
|---|---|
| Box-and-arrow flowcharts | flowchart TD/LR |
| Sequence arrows between components | sequenceDiagram |
| State machine diagrams | stateDiagram-v2 |
| Class/struct layouts with relationships | classDiagram |
| ER diagrams with relationships | erDiagram |
| Timeline/chronology | timeline |
| Git branch visualizations | gitGraph |
| Tree structures (except file trees) | mindmap |
| Pie-like proportions | pie |
| 2x2 matrices | quadrantChart |
| Bar/line chart sketches | xychart-beta |
| Flow/sankey diagrams | sankey-beta |
| Architecture boxes | architecture-beta or block-beta |
ASCII → Desmos Graph Detect and convert:
^ and > axesASCII/Plain Text → MathJax Detect and convert:
x^2 + y^2 = r^2 → $x^2 + y^2 = r^2$sqrt(x) or √x → $\sqrt{x}$sum(n=1 to inf) or Σ notation → $\sum_{n=1}^{\infty}$integral or ∫ notation → $\int$a/b in math context → $\frac{a}{b}$ASCII → TikZJax Diagram Use TikZJax when Mermaid/Desmos cannot handle:
| ASCII Pattern | Convert To |
|---|---|
| Geometric shapes with coordinates | tikz with \draw, \fill |
| Circuit schematic (resistors, capacitors) | tikz with circuitikz |
| Molecular structure (bonds, atoms) | tikz with chemfig |
| 3D axes or 3D shapes | tikz with tikz-3dplot |
| Commutative diagram (arrows, morphisms) | tikz with tikz-cd |
| Plotted data with precise points | tikz with pgfplots |

<replacement_rules>
| Source | Action |
|---|---|
| ASCII diagram in code block | DELETE the code block, INSERT Mermaid/Desmos |
| ASCII math notation | DELETE the ASCII, INSERT MathJax inline or block |
| Plain text description | KEEP the text, ADD visual after it |
File tree (├── └──) | DO NOT replace - leave as is |

Why good: ASCII box diagram with arrows = perfect Mermaid candidate. Structure is preserved, rendering is cleaner. </example>
<example type="good" conversion="ascii_sequence → mermaid"> **Original:** ``` Client Server Database | | | |--request---->| | | |---query------>| | |<--result------| |<--response---| | ```Enhancement:
sequenceDiagram
Client->>Server: request
Server->>Database: query
Database-->>Server: result
Server-->>Client: response
Why good: ASCII sequence diagram with clear message flow. Mermaid sequenceDiagram is the exact match. </example>
<example type="good" conversion="ascii_graph → desmos"> **Original:** ``` y ^ 4 | * 3 | * * 2 | * * 1 |* * +-------------> x 0 1 2 3 4 ```Enhancement:
y = -(x-2)^2 + 4
Why good: ASCII parabola sketch. Desmos renders the actual function interactively. </example>
<example type="good" conversion="ascii_math → mathjax"> **Original:** ``` The integral of x^2 from 0 to 1 equals 1/3:1 ∫ x^2 dx = [x^3/3] from 0 to 1 = 1/3 0
**Enhancement:**
$$\int_0^1 x^2 \, dx = \left[\frac{x^3}{3}\right]_0^1 = \frac{1}{3}$$
**Why good:** ASCII integral notation with limits. MathJax renders it properly.
</example>
<example type="bad" conversion="file_tree">
**Original:**
src/ ├── components/ │ ├── Header.tsx │ └── Footer.tsx └── utils/ └── helpers.ts
**DO NOT convert.** File trees are meant to be ASCII. They're universally understood and don't benefit from Mermaid mindmap conversion.
</example>
<example type="bad" conversion="simple_arrow">
**Original:**
input → process → output
**DO NOT convert.** Single-line arrow notation is concise and clear. A Mermaid flowchart would add unnecessary complexity.
</example>

**Enhancement:**
```tikz
\usepackage{circuitikz}
\begin{document}
\begin{circuitikz}[scale=1]
\draw (0,0) to[R, l=$R_1$] (2,0)
to[C, l=$C_1$] (4,0)
to[short] (4,-2)
to[battery1, l=$V$] (0,-2)
to[short] (0,0);
\end{circuitikz}
\end{document}
Why good: ASCII circuit diagram with resistor and capacitor. TikZJax with circuitikz renders proper electronic symbols. </example>
<example type="good" conversion="ascii_geometry → tikzjax"> **Original:** ``` B /|\ / | \ / | \ / |h \ / | \ A-----+-----C M ```Enhancement:
\begin{document}
\begin{tikzpicture}[scale=1]
\coordinate (A) at (0,0);
\coordinate (B) at (2,3);
\coordinate (C) at (4,0);
\coordinate (M) at (2,0);
\draw[thick, cyan] (A) -- (B) -- (C) -- cycle;
\draw[dashed, yellow] (B) -- (M);
\fill[red] (A) circle (3pt) node[below left] {$A$};
\fill[red] (B) circle (3pt) node[above] {$B$};
\fill[red] (C) circle (3pt) node[below right] {$C$};
\fill[gray] (M) circle (2pt) node[below] {$M$};
\node[right] at (2,1.5) {$h$};
\end{tikzpicture}
\end{document}
Why good: ASCII triangle with height. TikZJax renders clean geometry with proper labels and coloring. </example>
<example type="good" conversion="ascii_game_scene → tikzjax"> **Original:** ``` +---------------------------+ | Score: 100 Lives: 3 | +---------------------------+ | | | [Player] | | | | | [Enemy1] [Enemy2] | | | | ======================== | +---------------------------+ ```Enhancement:
\begin{document}
\begin{tikzpicture}[scale=1]
% Game frame
\draw[thick, gray] (0,0) rectangle (6,5);
% HUD
\fill[black] (0,4.2) rectangle (6,5);

\fill[red] (4,1.5) rectangle (4.8,2.3);
% Ground
\fill[brown] (0,0) rectangle (6,0.5);
\end{tikzpicture}
\end{document}
Why good: ASCII game layout. TikZJax renders a proper game scene with colored sprites and HUD elements. </example> </examples>
<examples category="text_to_visual"> <example type="good"> **Original text:** > The authentication flow works as follows: the user submits credentials, the server validates them against the database, if valid it generates a JWT token, otherwise it returns an error. The token is then stored in localStorage and sent with subsequent requests.Enhancement: Add a sequence diagram showing the flow between User, Server, and Database.
Why good: Multiple actors, multiple steps, clear message passing - a diagram genuinely clarifies. </example>
<example type="bad"> **Original text:** > To install, run `npm install`.Enhancement: Add a flowchart showing "Start → Run npm install → End"
Why bad: Trivial single step. The diagram adds nothing, just visual noise. </example>
<example type="good"> **Original text:** > The quadratic formula is x = (-b plus or minus sqrt(b^2 - 4ac)) / 2aEnhancement: Convert to: $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$
Why good: The formula is already there but hard to read. MathJax makes it beautiful. </example>
<example type="bad"> **Original text:** > Add 2 and 3 to get 5.Enhancement: Convert to: $2 + 3 = 5$
Why bad: Trivial arithmetic doesn't need LaTeX formatting. </example> </examples>
