# bench/chart.gnuplot — multi-panel SVG showing relay performance over git tags.
#
# Invoked by scripts/run_bench_update.sh with:
#   gnuplot -e "data_dir='...'" -e "output_file='...'" bench/chart.gnuplot
#
# The data_dir contains per-metric TSV files and a plot_commands.gnuplot
# fragment generated by the data-prep step that defines the actual plot
# directives (handling variable server columns).
