Pie Visualization

Pie Visualization

n_pie(
  data,
  id = NULL,
  value = NULL,
  label = NULL,
  render = c("svg", "canvas"),
  ...,
  width = NULL,
  height = NULL,
  elementId = NULL
)

Arguments

data	a data.frame contains value for create the pie
id	the name of the column used to represent the group.
value	column names for value.
label	column names for label. If not provided, id is used as the label by default.
render	"svg" (responsive) or "canvas". "canvas" is well suited for large data sets as it does not impact DOM tree depth, however you'll lose the isomorphic rendering ability.
...	additional arguments.
width, height	Must be a valid CSS unit (like '100%', '400px', 'auto') or a number, which will be coerced to a string and have 'px' appended.
elementId	element id of widgets

Value

a pie component
