-## Dashboards
-
-Dashboards are a useful way to communicate information visually and quickly.
-A dashboard-like look can be achieved with Quarto using document layout options like sidebars, tabsets, multi-column layouts, etc.
-
-For example, you can produce this dashboard:
-
-```{r}
-#| echo: false
-#| fig-alt: |
-#|   Quarto dashboard with the title "Diamonds dashboard". The first 
-#|   tab shows four plots of the diamonds dataset. The second tab 
-#|   shows summary statistics for price and carat of diamonds. The third 
-#|   tab shows an interactive data table of the first 100 diamonds.
-
-knitr::include_graphics("quarto/quarto-dashboard.png")
-```
-
-Using this code:
-
-```{r comment = "", echo = FALSE}
-cat(readr::read_file("quarto/quarto-dashboard.qmd"))
-```
