## Images
### Omnigraffle drawings
- Font: 12pt Guardian Sans Condensed / Ubuntu mono
- Export as 300 dpi png.
- Website font is 18 px = 13.5 pt, so scale dpi to match font sizes: 270 = 300 \* 12 / 13.5.
(I also verified this empirically by screenshotting.)

``` r
#| echo: FALSE
#| out.width: NULL
knitr::include_graphics("diagrams/transform.png", dpi = 270)
```
### Screenshots
- Make sure you're using a light theme.
For small interface elements (eg. toolbars), zoom in twice.
- Screenshot with Cmd + Shift + 4.
- Don't need to set dpi:
``` r
#| echo: FALSE
#| out.width: NULL
knitr::include_graphics("screenshots/rstudio-wg.png")
```
