An R package for creating interactive d3.js visualizations using htmlwidgets. Supports 17 chart types including scatter plots, line charts, bar charts, treemaps, and more — all composable through a piped API.
Usage
Build plots by piping layers together with myIO() and addIoLayer():
library(myIO)
myIO() |>
addIoLayer(
type = "point",
color = "#E69F00",
label = "points",
data = mtcars,
mapping = list(x_var = "wt", y_var = "mpg")
) |>
addIoLayer(
type = "line",
transform = "lm",
color = "red",
label = "trend",
data = mtcars,
mapping = list(x_var = "wt", y_var = "mpg")
