Radar Chart (Visualization)

Renders a multi-group radar chart using ggplot2 + coord_polar().

Usage

create_radar_viz(data, metrics, hrvar, fill_missing = "zero", caption = NULL)

Arguments

data

Output table from create_radar_calc().

metrics

Character vector of metric column names.

hrvar

Character string of grouping column name.

fill_missing

Character string specifying how to handle missing values. If "zero" (default), fill NA values as 0 for plotting. This ensures polygons close properly in the radar visualization.

caption

Character string for the plot caption. Typically the output of extract_date_range(data, return = "text") plus an index-mode label, as constructed by create_radar(). Defaults to NULL (no caption).

Value

ggplot object.
