This repo contains examples for creating simple analyses and histograms from the open data released by the CMS experiment at the LHC.

This repository contains several examples for creating simple analyses and histograms from the open data released by the CMS experiment at the LHC (see http://opendata.cern.ch). The data in the examples are in csv format and describe events containing two muons:

The examples here use two JavaScript libraries, Flot (http://www.flotcharts.org) and d3 (http://d3js.org) and the R language (http://www.r-project.org). To use the first two: in a terminal, in the opendata-histograms directory, run a simple HTTP server by typing the command

python -m SimpleHTTPServer

Then in a browser go to http://localhost:8000

To try the R example type each command at the R console prompt.
