the Urban Institute style guide, with [viridis] color scheme.
Replace [ggplot2] scale_colour_discrete with scale_colour_viridis_d

)Arguments
- base_size
base font size
- base_line_size
base line sizes
- base_rect_size
base rectangle sizes
- base_family
base font family: 'Open Sans' (default) or 'Lato'
- font_method
"extrafont" or "showtext"
- set_font
default is FALSE
- ...
Other arguments passed on to [discrete_scale()], [continuous_scale()], or [binned_scale] to control name, limits, breaks, labels and so forth.
- alpha
The alpha transparency, a number in [0,1], see argument alpha in
hsv.- begin, end
The (corrected) hue in
[0,1]at which the color map begins and ends.- direction
Sets the order of colors in the scale. If 1, the default, colors are ordered from darkest to lightest. If -1, the order of colors is reversed.
- option
A character string indicating the color map option to use. Eight options are available:
"magma"(or"A")"inferno"(or"B")"plasma"(or"C")"viridis"(or"D")"cividis"(or"E")"rocket"(or"F")"mako"(or"G")"turbo"(or"H")
- aesthetics
Character string or vector of character strings listing the name(s) of the aesthetic(s) that this scale works with. This can be useful to apply color settings to the `colour` and `fill` aesthetics at the same time, via `aesthetics = c("colour", "fill")`.
- values
if colours should not be evenly positioned along the gradient this vector gives the position (between 0 and 1) for each colour in the
coloursvector. Seerescale()for a convenience function to map an arbitrary range to between 0 and 1.- space
colour space in which to calculate gradient. Must be "Lab" - other values are deprecated.
- na.value
Missing values will be replaced with this value.
- guide
A function used to create a guide or its name. See
guides()for more information.
