livebook-dev/vega_lite

This system is an Elixir library that provides bindings for the Vega-Lite visualization specification. It enables developers to construct declarative graphics specifications through a pipeline-based API, supporting data initialization from values, URLs, or Table.Reader protocols. The library handles the translation of Elixir data structures into the JSON format required by Vega-Lite, including automatic normalization of option keys and type inference.

This change introduces the core \VegaLite\ module, providing a pipeline-based API for building declarative Vega-Lite graphics specifications in Elixir. Users can now initialize specs with \VegaLite.new/1\, parse existing JSON definitions via \VegaLite.from\_json/1\ (requiring the \Jason\ library), and construct visualizations using functions like \data\_from\_values/3\, \mark/2\, and \encode\_field/4\. The implementation automatically normalizes Elixir-style snake\_case options into the camelCase format required by the Vega-Lite specification.

The library adds a new \VegaLite.Data\ module that provides a \chart/3\ and \chart/4\ shorthand for creating visualizations directly from data implementing the \Table.Reader\ protocol, including automatic type inference for columns. Simultaneously, the existing \VegaLite.Export\ and \VegaLite.Viewer\ modules are marked as deprecated in favor of the external \:vega\_lite\_convert\ package, with their functions (such as \save!/3\, \to\_json/1\, and \show/1\) now emitting deprecation warnings to guide users toward the new conversion-based workflow.

Added comprehensive test coverage for VegaLite data specification functions; Added tests for the Data module shorthand API.

This entry marks the initial release of the VegaLite library (v0.1.11), establishing the core Elixir bindings to Vega-Lite. The project now depends on \table\ (\~\> 0.1.0) for data handling and \jason\ (\~\> 1.2) for JSON processing (dev/test only). It raises the minimum supported Elixir version to \~\> 1.12 and configures \ex\_doc\ (\~\> 0.24) for generating documentation, which is now included in the package metadata along with Apache-2.0 licensing and GitHub link information.
