#!/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 node 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.
