Wowchemy is designed to give technical content creators a seamless experience. You can focus on the content and Wowchemy handles the rest.

**Highlight your code snippets, take notes on math classes, and draw diagrams from textual representation.**

On this page, you'll find some examples of the types of technical content that can be rendered with Wowchemy.

## Examples

### Code

Wowchemy supports a Markdown extension for highlighting code syntax. You can customize the styles under the `syntax_highlighter` option in your `config/_default/params.yaml` file.

    ```python
    import pandas as pd
    data = pd.read_csv("data.csv")
    data.head()
    ```

renders as

```python
import pandas as pd
data = pd.read_csv("data.csv")
data.head()
```

### Mindmaps

Wowchemy supports a Markdown extension for mindmaps.

Simply insert a Markdown `markmap` code block and optionally set the height of the mindmap as shown in the example below.

A simple mindmap defined as a Markdown list:

<div class="highlight">
<pre class="chroma">
<code>
```markmap {height="200px"}
- Hugo Modules
  - wowchemy
  - wowchemy-plugins-netlify
  - wowchemy-plugins-netlify-cms
  - wowchemy-plugins-reveal
```
</code>
</pre>
</div>

renders as

```markmap {height="200px"}
- Hugo Modules
  - wowchemy
  - wowchemy-plugins-netlify
  - wowchemy-plugins-netlify-cms
  - wowchemy-plugins-reveal
```

A more advanced mindmap with formatting, code blocks, and math:

<div class="highlight">
<pre class="chroma">

      console.log('code block');
      ```
    - Math: $x = {-b \pm \sqrt{b^2-4ac} \over 2a}$
```

### Charts

Wowchemy supports the popular [Plotly](https://plot.ly/) format for interactive charts.

Save your Plotly JSON in your page folder, for example `line-chart.json`, and then add the `{{</* chart data="line-chart" */>}}` shortcode where you would like the chart to appear.

Demo:

{{< chart data="line-chart" >}}

You might also find the [Plotly JSON Editor](http://plotly-json-editor.getforge.io/) useful.

### Math

Wowchemy supports a Markdown extension for $\LaTeX$ math. You can enable this feature by toggling the `math` option in your `config/_default/params.yaml` file.

To render _inline_ or _block_ math, wrap your LaTeX math with `{{</* math */>}}$...${{</* /math */>}}` or `{{</* math */>}}$$...$${{</* /math */>}}`, respectively. (We wrap the LaTeX math in the Wowchemy _math_ shortcode to prevent Hugo rendering our math as Markdown. The _math_ shortcode is new in v5.5-dev.)

Example **math block**:

```latex
{{</* math */>}}
$$
\gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}
$$
{{</* /math */>}}
```

renders as

{{< math >}}
$$\gamma_{n} = \frac{ \left | \left (\mathbf x_{n} - \mathbf x_{n-1} \right )^T \left [\nabla F (\mathbf x_{n}) - \nabla F (\mathbf x_{n-1}) \right ] \right |}{\left \|\nabla F(\mathbf{x}_{n}) - \nabla F(\mathbf{x}_{n-1}) \right \|^2}$$
{{< /math >}}

Example **inline math** `{{</* math */>}}$\nabla F(\mathbf{x}_{n})${{</* /math */>}}` renders as {{< math >}}$\nabla F(\mathbf{x}_{n})${{< /math >}}.

Example **multi-line math** using the math linebreak (`\\`):

```latex
{{</* math */>}}
$$f(k;p_{0}^{*}) = \begin{cases}p_{0}^{*} & \text{if }k=1, \\
1-p_{0}^{*} & \text{if }k=0.\end{cases}$$
{{</* /math */>}}
```

renders as

{{< math >}}

$$
f(k;p_{0}^{*}) = \begin{cases}p_{0}^{*} & \text{if }k=1, \\
1-p_{0}^{*} & \text{if }k=0.\end{cases}
$$

{{< /math >}}

### Diagrams

Wowchemy supports a Markdown extension for diagrams. You can enable this feature by toggling the `diagram` option in your `config/_default/params.toml` file or by adding `diagram: true` to your page front matter.

An example **flowchart**:

    ```mermaid
    graph TD
    A[Hard] -->|Text| B(Round)
    B --> C{Decision}
    C -->|One| D[Result 1]
    C -->|Two| E[Result 2]
    ```

renders as

```mermaid
graph TD
A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
```

An example **sequence diagram**:

    ```mermaid
    sequenceDiagram
    Alice->>John: Hello John, how are you?
    loop Healthcheck
        John->>John: Fight against hypochondria
    end
    Note right of John: Rational thoughts!
    John-->>Alice: Great!
    John->>Bob: How about you?
    Bob-->>John: Jolly good!
    ```

renders as

```mermaid
sequenceDiagram
Alice->>John: Hello John, how are you?
loop Healthcheck
    John->>John: Fight against hypochondria
end
Note right of John: Rational thoughts!
John-->>Alice: Great!
John->>Bob: How about you?
Bob-->>John: Jolly good!
```

An example **Gantt diagram**:

    ```mermaid
    gantt
    section Section
    Completed :done,    des1, 2014-01-06,2014-01-08
    Active        :active,  des2, 2014-01-07, 3d
    Parallel 1   :         des3, after des1, 1d
    Parallel 2   :         des4, after des1, 1d
    Parallel 3   :         des5, after des3, 1d
    Parallel 4   :         des6, after des4, 1d
    ```

renders as

```mermaid
gantt
section Section
Completed :done,    des1, 2014-01-06,2014-01-08
Active        :active,  des2, 2014-01-07, 3d
Parallel 1   :         des3, after des1, 1d
Parallel 2   :         des4, after des1, 1d
Parallel 3   :         des5, after des3, 1d
Parallel 4   :         des6, after des4, 1d
```

An example **class diagram**:

    ```mermaid
    classDiagram
    Class01 <|-- AveryLongClass : Cool
    Class03 *-- Class04
    Class05 o-- Class06
    Class07 .. Class08
    Class09 --> C2 : Where am i?
    Class09 --* C3
    Class09 --|> Class07
    Class07 : equals()
    Class07 : Object[] elementData
    Class01 : size()
    Class01 : int chimp
    Class01 : int gorilla
    Class08 <--> C2: Cool label
    ```

renders as

```mermaid
classDiagram
Class01 <|-- AveryLongClass : Cool
Class03 *-- Class04
Class05 o-- Class06
Class07 .. Class08
Class09 --> C2 : Where am i?
Class09 --* C3
Class09 --|> Class07
Class07 : equals()
Class07 : Object[] elementData
Class01 : size()
Class01 : int chimp
Class01 : int gorilla
Class08 <--> C2: Cool label
```

An example **state diagram**:

    ```mermaid
    stateDiagram
    [*] --> Still
    Still --> [*]
    Still --> Moving
    Moving --> Still
    Moving --> Crash
    Crash --> [*]
    ```

renders as

```mermaid
stateDiagram
[*] --> Still
Still --> [*]
Still --> Moving
Moving --> Still
Moving --> Crash
Crash --> [*]
```

### Todo lists

You can even write your todo lists in Markdown too:

```markdown
- [x] Write math example
  - [x] Write diagram example
- [ ] Do something else
```

renders as

- [x] Write math example
  - [x] Write diagram example
- [ ] Do something else

### Tables

Save your spreadsheet as a CSV file in your page's folder and then render it by adding the _Table_ shortcode to your page:

```go
{{</* table path="results.csv" header="true" caption="Table 1: My results" */>}}
```

renders as

{{< table path="results.csv" header="true" caption="Table 1: My results" >}}

### Callouts

Academic supports a [shortcode for callouts](https://wowchemy.com/docs/content/writing-markdown-latex/#callouts), also referred to as _asides_, _hints_, or _alerts_. By wrapping a paragraph in `{{%/* callout note */%}} ... {{%/* /callout */%}}`, it will render as an aside.

```markdown
{{%/* callout note */%}}
A Markdown aside is useful for displaying notices, hints, or definitions to your readers.
{{%/* /callout */%}}
```

renders as

{{% callout note %}}
A Markdown aside is useful for displaying notices, hints, or definitions to your readers.
{{% /callout %}}

### Spoilers

Add a spoiler to a page to reveal text, such as an answer to a question, after a button is clicked.

```markdown
{{</* spoiler text="Click to view the spoiler" */>}}
You found me!
{{</* /spoiler */>}}
```

renders as

{{< spoiler text="Click to view the spoiler" >}} You found me! {{< /spoiler >}}

### Icons

Academic enables you to use a wide range of [icons from _Font Awesome_ and _Academicons_](https://wowchemy.com/docs/getting-started/page-builder/#icons) in addition to [emojis](https://wowchemy.com/docs/content/writing-markdown-latex/#emojis).

Here are some examples using the `icon` shortcode to render icons:

```markdown
{{</* icon name="terminal" pack="fas" */>}} Terminal  
{{</* icon name="python" pack="fab" */>}} Python  
{{</* icon name="r-project" pack="fab" */>}} R
```

renders as

{{< icon name="terminal" pack="fas" >}} Terminal  
{{< icon name="python" pack="fab" >}} Python  
{{< icon name="r-project" pack="fab" >}} R
