RubyMatrixToSvg is a pure Ruby library without any dependencies that allows you to create a svg string from a matrix of colors that you've defined.

Add this line to your application's Gemfile:

gem 'ruby_matrix_to_svg'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby_matrix_to_svg

Create a svg matrix string from your matrix filled with colors.

svg_matrix = RubyMatrixToSvg.matrix_to_svg("ruby_matrix_title", matrix)

where matrix is the Array of columns and rows filled with colours.

Returned String can be used in a simple way in your HTML document settting a size for your image

<img src="data:image/svg+xml;utf8, <%= raw(svg_matrix) %>" width="200px">

##Example

matrix = [
    ['#fff', '#fff', '#fff'],
    ['#000', '#000', '#000'],
    ['#fff', '#fff', '#fff'],
    ['#000', '#000', '#000']
  ]

matrix_string = RubyMatrixToSvg.matrix_to_svg("ruby_matrix_title", matrix)
