## Markdown Strings
The "Markdown Strings" feature enhances flowcharts and mind maps by offering a more versatile string type, which supports text formatting options such as bold and italics, and automatically wraps text within labels.
```mermaid-example
%%{init: {"flowchart": {"htmlLabels": false}} }%%
flowchart LR
subgraph "One"
a("`The **cat**
in the hat`") -- "edge label" --> b{{"`The **dog** in the hog`"}}
end
subgraph "`**Two**`"
c("`The **cat**
in the hat`") -- "`Bold **edge label**`" --> d("The dog in the hog")
end
```
```mermaid
%%{init: {"flowchart": {"htmlLabels": false}} }%%
flowchart LR
subgraph "One"
a("`The **cat**
in the hat`") -- "edge label" --> b{{"`The **dog** in the hog`"}}
end
subgraph "`**Two**`"
c("`The **cat**
in the hat`") -- "`Bold **edge label**`" --> d("The dog in the hog")
end
```
Formatting:
- For bold text, use double asterisks \*\* before and after the text.
- For italics, use single asterisks \* before and after the text.
- With traditional strings, you needed to add <br> tags for text to wrap in nodes. However, markdown strings automatically wrap text when it becomes too long and allows you to start a new line by simply using a newline character instead of a <br> tag.
This feature is applicable to node labels, edge labels, and subgraph labels.
## Interaction
It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.

## Integrating with your library/website.
Mindmap uses the experimental lazy loading & async rendering features which could change in the future. From version 9.4.0 this diagram is included in mermaid but use lazy loading in order to keep the size of mermaid down. This is important in order to be able to add additional diagrams going forward.

"A timeline is a type of diagram used to illustrate a chronology of events, dates, or periods of time. It is usually presented graphically to indicate the passing of time, and it is usually organized chronologically. A basic timeline presents a list of events in chronological order, usually using dates as markers. A timeline can also be used to show the relationship between events, such as the relationship between the events of a person's life.

You can customize the color scheme using the `cScale0` to `cScale11` theme variables. Mermaid allows you to set unique colors for up-to 12, where `cScale0` variable will drive the value of the first section or time-period, `cScale1` will drive the value of the second section and so on.

In case you have more than 12 sections, the color scheme will start to repeat.
NOTE: Default values for these theme variables are picked from the selected theme. If you want to override the default values, you can use the `initialize` call to add your custom theme variable values.

## Markdown Strings
The "Markdown Strings" feature enhances flowcharts and mind maps by offering a more versatile string type, which supports text formatting options such as bold and italics, and automatically wraps text within labels.
```mermaid-example

in the hat`") -- "edge label" --> b{{"`The **dog** in the hog`"}}
end
subgraph "`**Two**`"
c("`The **cat**
in the hat`") -- "`Bold **edge label**`" --> d("The dog in the hog")
end
```
Formatting:
- For bold text, use double asterisks \*\* before and after the text.
- For italics, use single asterisks \* before and after the text.
- With traditional strings, you needed to add <br> tags for text to wrap in nodes. However, markdown strings automatically wrap text when it becomes too long and allows you to start a new line by simply using a newline character instead of a <br> tag.
This feature is applicable to node labels, edge labels, and subgraph labels.
## Interaction
It is possible to bind a click event to a node, the click can lead to either a javascript callback or to a link which will be opened in a new browser tab. **Note**: This functionality is disabled when using `securityLevel='strict'` and enabled when using `securityLevel='loose'`.

## Integrating with your library/website.
Mindmap uses the experimental lazy loading & async rendering features which could change in the future. From version 9.4.0 this diagram is included in mermaid but use lazy loading in order to keep the size of mermaid down. This is important in order to be able to add additional diagrams going forward.

### Customizing Color scheme
You can customize the color scheme using the `cScale0` to `cScale11` theme variables. Mermaid allows you to set unique colors for up-to 12, where `cScale0` variable will drive the value of the first section or time-period, `cScale1` will drive the value of the second section and so on.
You can customize the color scheme using the `cScale0` to `cScale11` theme variables. Mermaid allows you to set unique colors for up-to 12 sections, where `cScale0` variable will drive the value of the first section or time-period, `cScale1` will drive the value of the second section and so on.
In case you have more than 12 sections, the color scheme will start to repeat.
NOTE: Default values for these theme variables are picked from the selected theme. If you want to override the default values, you can use the `initialize` call to add your custom theme variable values.
