#!/usr/bin/env Rscript
# To use this to graph some benchmarks, install R (http://www.r-project.org/)
# and ggplot (http://ggplot2.org/).
#
# Once installed, you can generate some CSV output with a command like this:
#
# $ OUTPUT_FORMAT=csv iojs benchmark/http/client-request-body.js > data.csv
# $ ./benchmark/plot_csv.R data.csv data.png bytes type
#
# Where the 3rd argument to this script is the graph's X coordinate, the 4th is
# how the output is grouped, and the Y coordinate defaults to result.

# read data

# plot and save
