#' Creating Boxplot for a dataset
#'
#' @description The box and whiskers plot displays the distribution of a continuous variable. 
#' It visualises five summary statistics (the median, two hinges and two whiskers), and all "outlying" points individually. 
#' The `ggplot2` package is used here for creating the boxplot.
#'
#' @param data Proteomics expression dataset (original or normalized dataset)
#'
#' @return Interactive box and whiskers plot
#'
#' @details This can also be used for comparing the original dataset with the normalized dataset.
