Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.

Error: Chart, Chart::Bars, Chart::Base, Chart::BrushStyles, Chart::Color, Chart::Color::Named, Chart::Color::Scheme, Chart::Composite, Chart::Constants, Chart::Direction, Chart::ErrorBars, Chart::HorizontalBars, Chart::Lines, Chart::LinesPoints, Chart::Mountain, Chart::Pareto, Chart::Pie, Chart::Points, Chart::Split, Chart::StackedBars

Fix the version numbers so that version::is_lax($version) returns true.

Add all modules contained in this distribution to the META.yml field 'provides'. Module::Build or Dist::Zilla::Plugin::MetaProvides do this automatically for you.

Add a 'repository' resource to the META.yml via 'meta_add' accessor (for Module::Build) or META_ADD parameter (for ExtUtils::MakeMaker).
