## Quarto

Quarto documentation and gallery can be found on their [website](https://quarto.org/).

Below are some examples of the features that were added to RMarkdown notebooks.

## Automatic Figure labeling

@fig-airquality explores the impact of temperature on ozone level.

```{r}
#| label: fig-airquality
#| fig-cap: Temperature and ozone level.
#| warning: false

library(ggplot2)
data(airquality)

ggplot(airquality, aes(Temp, Ozone)) + 
  geom_point() + 
  geom_smooth(method = "loess"
)
```

## Mermaid Diagrams

Quarto has native support for embedding Mermaid and Graphviz diagrams. This enables you to create flowcharts, sequence diagrams, state diagrams, gantt charts, and more using a plain text syntax inspired by markdown:

```{mermaid}
%%| label: fig-mermaid
%%| fig-width: 6
%%| fig-cap: Mermaid Diagrams
flowchart LR
  A[qmd] --> B(Knitr)
  A[qmd] --> C(Jupyter)
  B(Knitr) --> D[md]
  C(Jupyter) --> D[md]
  D[md] --> E(pandoc)
  E(pandoc) --> F(HTML)
  E(pandoc) --> G(PDF)
  E(pandoc) --> H(Word)
  E(pandoc) --> I{and more}
```

## Graphviz Diagrams

```{dot}
//| label: fig-dot
//| fig-width: 3
//| fig-cap: Graphviz diagrams
graph G {
  layout=neato
  qmd -- Knitr;
  qmd -- Jupyter;
  Knitr -- md;
  Jupyter -- md;
  md -- pandoc;
  pandoc -- HTML;
  pandoc -- PDF;
  pandoc -- Word;
  pandoc -- more;
}
```
