Adds mojo-asciichart v1.1.2 - Nice-looking lightweight console ASCII line charts for Mojo.

Version update: v1.1.1 → v1.1.2 includes pre-commit whitespace fixes.

First submission following the modular-community standards guide.

Package features:

  • Native Mojo port of the popular asciichartpy (Python) and asciichart (JavaScript) libraries
  • Generate beautiful ASCII line charts in your terminal with no dependencies
  • Basic plot() function for single series data
  • Configurable height, min/max bounds, custom formatting
  • Automatic data scaling and min/max detection
  • NaN value handling (renders gaps in data)
  • UTF-8 box-drawing characters for smooth curves
  • ANSI color support with 6 predefined themes (default, blue, matrix, fire, ocean, rainbow)
  • Python interop tests validating compatibility with asciichartpy
  • Pixel-perfect output matching the original Python implementation
  • Performance: 1.4-4.3x faster than Python's asciichartpy
  • Comprehensive test suite with 29 tests passing

Use case: Perfect for command-line tools, monitoring dashboards, debugging output, and any Mojo application needing quick data visualization without GUI dependencies.

Compliance checklist:

  • ✅ Package image (126KB PNG) for builds.modular.com
  • ✅ CodeQL scanning enabled
  • ✅ CodeQL badge in README
  • ✅ Apache-2.0 license
  • ✅ Git tag v1.1.2 exists
  • ✅ recipe.yaml with proper structure
  • ✅ test_package.mojo validates core functionality
  • ✅ Comprehensive README and documentation
  • ✅ Performance benchmarks comparing to Python

Update:

  • migrated mojo-asciichart to Mojo 0.26.1.
  • In the mojo-asciichart repo, MAX is now pinned to '>=26.1.0,<27', tests were updated to avoid direct String indexing and deprecated ListFloat64 constructors, and all 5 test suites pass under 0.26.1 (including core Python interop tests).
  • The local mojo-asciichart recipe.yaml now uses context.mojo_version = '=0.26.1' and the same pin has been applied here in recipes/mojo-asciichart/recipe.yaml.
  • Some advanced Python-list → Mojo-list interop tests have been temporarily relaxed pending a 0.26.1-friendly PythonObject conversion API, but cross-language output comparisons (simple, sine, height, flat) remain fully covered.

The pre-commit whitespace check seems really temperamental - I am enforcing it in my repo but it fails in CI? @yetalit

@Mjboothaus Those whitespaces I removed were causing the problem.
