== DESCRIPTION

ruby-googlechart is a ruby library which provides object-oriented
access to the Google Charts API.

This library has largely been done as an exercise. These other ruby
libraries are more mature and may be better suited to your needs:

* http://googlecharts.rubyforge.org/
* http://code.google.com/p/gchartrb/

== FEATURES

* Line charts (line, XY, sparkline)
* Bar charts (horizontal, vertical, grouped, stacked)

== SYNOPSIS
  
  require 'google_chart'
  
  url = GoogleChart.Line(:data => [1, nil, 2, 8, 1])
  url = GoogleChart.Bar(:data => [5, 23, 6, 14])
  
  url = GoogleChart.Bar do |c|
    c.axes     = {:x => %w[Q1 Q2 Q3 Q4], :y => 0..400}
    c.data     = [335, 285, 240, 220, 160, 175, 200, 205]
    c.encoding = :extended
    c.scale    = 0..400
    c.size     = '800x375'
    c.style    = :dash
    c.title    = "Are You Pondering What I'm Pondering?"
    c.type     = :line
  end
  url = GoogleChart.Bar do |c|
    c.horizontal = true
    c.grouped    = true
    c.data       = [[5, 6, 7, 8], [23, 14, 17, 16]]
    c.encoding   = :text
    c.title      = 'Lorem Ipsum Dolor'
  end
  
  chart = GoogleChart::LineChart.new
  chart.type  = :sparkline
  chart.size  = '75x25'
  chart.data  = [1, 1, 2, 3, 5, 8, 13]
  chart.color = 'ff0000'
  url = chart.to_url

Critical CVE

Contains a high severity Common Vulnerability and Exposure (CVE).

What is a CVE?

High CVE

Uses debug, reflection and dynamic code execution features.

What is debug access?
