Waxy

Waxy is an experimental visualization tool to generate SVG hexagons and their layouts, it is in Ruby.

The library is solely possible thanks to the wonderful Amit Patel sharing his knowledge at the Red Blob Games blog, in particular the hexagon tutorial. Most of the serious code herein is simply an implementation of the metacode therein. All of the misinterpretations and problems are ours, not Amit's!

Add this line to your application's Gemfile:

gem 'waxy'

And then execute:

$ bundle

Or install it yourself as:

$ gem install waxy

The API will most certainly change if/when the code is deemed more than a playground. Nothing is really optimized.

require 'waxy'

srand

layout = Waxy::Geometry::Layout.new(
  Waxy::Geometry::Orientation::LAYOUT_POINTY,
  Waxy::Geometry::Point.new(20,20), # size
  Waxy::Geometry::Point.new(20, 20), # start
  5.0 # padding
) 

meta = []

(0..400).each do |i|
  a = Waxy::Meta.new
  a.size = (0..5).collect{ rand(0.0..1.0) } 
  a.stroke = 'purple'
  a.link = 'http://127.0.0.1:3000/'
  a.link_title = "RECORD #{i}"
  
  meta.push a 
end

meta.sort!{ |a,b| a.sum_size <=> b.sum_size }

c = Waxy::Render::Svg::Canvas.new(1000, 1000)
c.body << Waxy::Render::Svg.rectangle(layout, meta, 5)
puts c.to_svg

then

ruby go.rb > svg.html
open svg.html

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
