+Sometimes it's a delight to see plots in a table. Here we provide recipes for a few common tasks using both `kableExtra`'s built-in functions and external libraries, including `ggplot2`, `sparkline` and `plotly`.
 
+In terms of `kableExtra`'s built-in plotting functions, since version 1.2.1, `kableExtra` includes these functions for the most common plotting tasks. Since I don't want to introduce an entire `ggplot2` dependency to this package, all these plotting functions were developed using base-R `plot`. Here I need to acknowledge the significant contribution from Bill Evans (@r2evans on github and SO), who wrote the general `spec_plot` function and improved the coding structure of these `spec_***` plotting functions.
