 #' @title Client-side function to generate hazard ratio plots in DataSHIELD
-#' @description This function creates a ggplot visualization for hazard ratio analysis
-#' by getting the prediction data from the server-side acmPlotDS function.
-#'
-#' @details This function takes a prediction object created by ds.Predict and generates
-#' a customizable ggplot visualization. The function allows customization of colors,
-#' line sizes, axis labels, and more.

+#' @description Builds a ggplot hazard ratio curve per study using prediction data retrieved from a server-side prediction object.
+#' @details This function calls the server-side aggregate function to retrieve summarized prediction data for a named server-side object, then builds one ggplot2 plot per study locally in R using ggplot2::ggplot, geom_line, geom_hline, and related layers. It also relies on the rms package being available locally for plotting support. Server function called: `acmPlotDS`.

+#' @return Returns a plain R list of ggplot objects, one per study/data source, built from the aggregated prediction data; no additional disclosure control is applied within this function since only already-aggregated summary data is used for plotting.
