A set of Asciidoctor extensions that adds a chart block and block macro for including charts powered by https://c3js.org/[C3.js], https://gionkunz.github.io/chartist-js/[Chartist], or https://www.chartjs.org/[Chart.js] in your AsciiDoc document.
== Prerequisites
All that's needed is Ruby 2.5 or better (or JRuby 9.2 or better) and a few Ruby gems (including at least Asciidoctor 2.0.0), which we explain how to install in the next section.
To check if you have Ruby available, use the ruby command to query the version installed:
$ ruby -e 'puts RUBY_VERSION'
Make sure this command reports a Ruby version that's at least 2.5. If so, you may proceed.
== Getting Started
You can get {project-name} by <<install-the-published-gem,installing the published gem>>. ifndef::env-site[You can also <<development,run the code from source>> if you want to use a development version or participate in development.]
=== Install the Published Gem
To install {project-name}, first make sure you have satisfied the <<Prerequisites,prerequisites>>. Then, install the gem from RubyGems.org using the following command:
$ gem install asciidoctor-chart
